Dear Stockholder:
 
    As you may be aware, First Consulting Group, Inc., a Delaware corporation
("FCG"), and Integrated Systems Consulting Group, Inc., a Pennsylvania
corporation ("ISCG"), have entered into an Agreement and Plan of Merger and
Reorganization dated as of September 9, 1998 (the "Reorganization Agreement")
providing for the acquisition of ISCG by FCG as described below. Pursuant to the
Reorganization Agreement, a special meeting of the stockholders of FCG (the "FCG
Special Meeting") will be held at 111 W. Ocean Boulevard, 4th Floor, Long Beach,
California 90802 on [           ], 1998 at 9:00 a.m. local time.
 
   
    At the FCG Special Meeting you will be asked to consider and vote upon a
proposal to approve the issuance of shares of Common Stock, par value $0.001 per
share, of FCG ("FCG Common Stock") pursuant to the Reorganization Agreement.
Pursuant to the Reorganization Agreement, a wholly-owned subsidiary of FCG will
be merged with and into ISCG (the "Merger"). Upon consummation of the Merger,
ISCG will become a wholly-owned subsidiary of FCG. In the Merger, each
outstanding share of Common Stock, par value $0.005 per share, of ISCG ("ISCG
Common Stock"), other than shares of ISCG Common Stock held by ISCG shareholders
who properly exercise their dissenters' rights, will be converted into the right
to receive 0.77 of a share of FCG Common Stock (as adjusted for any stock split,
stock dividend, reverse stock split, reclassification, recapitalization or
similar transaction) (the "Exchange Ratio"). The Merger is described more fully
in the accompanying Joint Proxy Statement/Prospectus.
    
 
    After careful consideration, the Board of Directors of FCG (the "FCG Board
of Directors") has unanimously approved the Reorganization Agreement and the
Merger, and has concluded they are fair to, and in the best interests of, FCG
and its stockholders. The FCG Board of Directors unanimously recommends that you
vote in favor of the issuance of shares of FCG Common Stock pursuant to the
Reorganization Agreement.
 
    In the materials accompanying this letter you will find a Notice of Special
Meeting of Stockholders, a Joint Proxy Statement/Prospectus relating to the
proposal to be voted upon at the FCG Special Meeting and a Proxy Card. The Joint
Proxy Statement/Prospectus more fully describes the proposed transaction and the
proposal before the FCG stockholders.
 
    All FCG stockholders are cordially invited to attend the FCG Special Meeting
in person. If you attend the FCG Special Meeting, you may vote in person if you
wish even though you have previously returned your completed proxy card. WHETHER
OR NOT YOU PLAN TO ATTEND THE FCG SPECIAL MEETING, IT IS IMPORTANT THAT YOUR
SHARES BE REPRESENTED AND VOTED, REGARDLESS OF HOW MANY SHARES YOU HOLD.
APPROVAL OF THE ISSUANCE OF SHARES OF FCG COMMON STOCK REQUIRES THE AFFIRMATIVE
VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES OF FCG COMMON STOCK
PRESENT IN PERSON OR REPRESENTED BY PROXY AT THE FCG SPECIAL MEETING AND
ENTITLED TO VOTE THEREAT. THEREFORE, PLEASE COMPLETE, SIGN, DATE AND RETURN YOUR
PROXY CARD IN THE ENCLOSED ENVELOPE.
 
    On behalf of the FCG Board of Directors, I thank you for your support and
ask you to vote in favor of the issuance of shares in this transaction.

                                   PROSPECTUS
    
 
   
    The Boards of Directors of First Consulting Group, Inc. ("FCG") and
Integrated Systems Consulting Group, Inc. ("ISCG") have agreed to merge a
subsidiary of FCG with and into ISCG. After the merger, ISCG will operate as a
wholly-owned subsidiary of FCG. Under the terms of the merger, FCG will pay to
ISCG shareholders 0.77 (which is referred to in this Joint Proxy
Statement/Prospectus as the "Exchange Ratio") of a share of FCG Common Stock for
each share of ISCG Common Stock that they own. In lieu of receiving FCG Common
Stock, ISCG shareholders have the right to demand dissenter's rights. ISCG
shareholders who properly demand dissenter's rights will receive in cash the
fair value of the shares of ISCG Common Stock that they held prior to the
merger. The fair value of ISCG Common Stock would be determined by a court or by
agreement between ISCG and the ISCG shareholder. We estimate that the shares of
FCG Common Stock to be issued to ISCG shareholders will represent approximately
   % of the outstanding FCG Common Stock after the merger.
    
 
   
    The merger cannot be completed unless the holders of FCG and ISCG Common
Stock approve the matters described in this document. We have scheduled special
meetings for the FCG stockholders and ISCG shareholders to vote on the matters
described in this document. At the FCG Special Meeting, FCG stockholders will be
asked to approve the issuance of shares of FCG Common Stock in the merger. At
the ISCG Special Meeting, ISCG shareholders will be asked to adopt and approve
the merger agreement and approve the merger of the subsidiary of FCG with and
into ISCG. YOUR VOTE IS VERY IMPORTANT.
    
 
   
    Whether or not you plan to attend your special meeting, please take the time
to vote by completing and mailing the enclosed proxy card to us. If you sign,
date and mail your proxy card without indicating how you want to vote, your
proxy will count as a vote in favor of the merger.
    
 
   
    You may vote at your special meeting if you own shares as of the close of
business on [            , 1998]. The dates, times and places of the Special
Meetings are as follows:

                           ABOUT THE FCG/ISCG MERGER
    
 
   
<TABLE>
<C>        <S>
   Q:      WHY ARE THE TWO COMPANIES PROPOSING TO MERGE?
 
   A:      We believe that the merger will create a
           combined company that will be able to:
 
           - respond quickly and effectively to emerging
             opportunities in the healthcare industry
 
           - offer a broader range and scope of services
           to the pharmaceutical and biotechnology
             industries
 
           - compete more effectively in providing these
             services
 
   Q:      AS AN ISCG SHAREHOLDER, WHAT WILL I RECEIVE
           IN THE MERGER?
 
   A:      Unless you properly exercise your dissenters'
           rights, you will receive 0.77 of a share of
           FCG Common Stock in exchange for each share
           of ISCG Common Stock that you own. For
           example, if you own 100 shares of ISCG Common
           Stock, you will receive 77 shares of FCG
           Common Stock in exchange for your shares.
 
   Q:      AS A FCG STOCKHOLDER, WILL I RECEIVE
           ADDITIONAL SHARES OF FCG COMMON STOCK IN THE
           MERGER?
 
   A:      You will continue to hold the same number of
           shares of FCG Common Stock after the merger.
           Additional shares of FCG Common Stock will be
           issued in the merger.
 
   Q:      WHEN ARE THE STOCKHOLDERS' MEETINGS RELATING
           TO THE MERGER AND WHAT SPECIFIC PROPOSALS
           WILL I BE ASKED TO CONSIDER?
 
   A:      The FCG special meeting will take place on
                     1998. At the FCG special meeting,
           FCG stockholders will be asked to approve the
           issuance of FCG Common Stock to ISCG
           shareholders in the merger. The Board of
           Directors of FCG unanimously recommends
           voting in favor of this proposal.
           The ISCG Special Meeting will take place on
                     1998. At the ISCG Special Meeting,
           ISCG shareholders will be asked to approve
           and adopt the merger agreement and approve
           the merger. The Board of Directors of ISCG
           unanimously recommends voting in favor of
           these proposals.
 
   Q:      IF I AM NOT GOING TO ATTEND THE STOCKHOLDER
           MEETING, SHOULD I RETURN MY PROXY CARD
           INSTEAD?
 
   A:      Yes. Please fill out and sign your proxy card
           and mail it to us in the enclosed return
           envelope as soon as possible. Returning your
           proxy card ensures that your shares will be
           represented at the special meeting.
 
   Q:      WHAT DO I DO IF I WANT TO CHANGE MY VOTE?
 
   A:      Send in a later-dated, signed proxy card to
           your company's Secretary before the special
           meeting or attend the special meeting in
           person and vote.
   Q:      SHOULD I SEND IN MY STOCK CERTIFICATES NOW?
 
   A:      No. After the merger is completed, we will
           send ISCG shareholders written instructions
           for exchanging their stock certificates. FCG
           stockholders will keep their current
           certificates.
 
   Q:      WHEN DO YOU EXPECT THE MERGER TO BE
           COMPLETED?
 
   A:      We are working to complete the merger as
           quickly as possible. We hope to complete the
           merger within a few days of satisfying the
           conditions of the merger agreement, including
           conditions relating to stockholder approval.
 
   Q:      WHAT ARE DISSENTERS' RIGHTS AND HOW CAN I
           PROPERLY EXERCISE THEM?
 
   A:      Dissenters' rights allow ISCG shareholders to
           receive the fair value of their shares of
           ISCG Common Stock in cash in lieu of FCG
           Common Stock. To exercise dissenters' rights,
           you must (1) notify ISCG of your intent to
           exercise dissenters' rights, (2) effect no
           change in your ownership in ISCG and (3)
           refrain from voting in favor of the merger.
           For a more detailed description of the
           procedures ISCG shareholders must follow to
           properly exercise their dissenters' rights,
           see "Approval of the Merger and Related
           Transactions--Rights of Dissenting
           Shareholders of ISCG" beginning on page 59 of
           this document. You should also read carefully
           and in its entirety the full text of the
           requirements of Pennsylvania law to exercise
           dissenters' rights is attached as Appendix F
           to this document. You should read this text
           carefully and in its entirety. FCG
           stockholders are not entitled to dissenters'
           rights in the merger.
 
   Q:      WHAT ARE THE TAX CONSEQUENCES TO STOCKHOLDERS
           OF THE MERGER?
 
   A:      We intend that the merger be treated as a
           tax-free reorganization for federal income
           tax purposes. ISCG shareholders should not
           recognize gain or loss on the exchange of
           their stock, other than taxes on cash
           received for a fractional share. FCG
           stockholders should not recognize any gain or
           loss in connection with the merger. Tax
           matters, however, are very complicated and
           the tax consequences of the merger to you
           will depend on the facts of your particular
           situation. We encourage you to contact your
           tax advisors to determine the tax
           consequences of the merger to you. To review
           the tax consequences to FCG and ISCG
           stockholders in greater detail, see pages 56
           to 58 of this Joint Proxy
           Statement/Prospectus.

    THE MERGER AGREEMENT IS ATTACHED AS APPENDIX A TO THIS DOCUMENT. WE
ENCOURAGE YOU TO READ THE MERGER AGREEMENT. IT IS THE LEGAL DOCUMENT GOVERNING
THE MERGER.
    
 
   
When the Merger Will Occur
    
 
   
    The merger will take place on a date agreed to by FCG and ISCG. This date
will be no later than the second business day after all of the conditions to
closing contained in the merger agreement have been satisfied or waived.
Assuming that our companies satisfy or waive all of the conditions in the merger
agreement, we anticipate that the merger will occur on or before [           ],
1998. For more information on regulatory matters and conditions of the merger,
see "Approval of the Merger and Related Transactions--Regulatory Matters"
beginning on page 58 and "The Reorganization Agreement-- Conditions to the
Merger" beginning on page 64.
    
 
   
What Shareholders Will Receive in the Merger
    
 
   
    If the merger is approved, ISCG shareholders, other than those who properly
exercise dissenters' rights, will receive 0.77 of a share of FCG Common Stock
for each share of ISCG Common Stock they own prior to the merger. Similarly,
each option to purchase ISCG Common Stock will convert into an option to
purchase 77% as many shares in FCG Common
    
 
                                       5
<PAGE>
   
Stock at an adjusted exercise price. FCG will assume each ISCG option in
accordance with the terms of the stock option plan under which the option was
issued and the stock option agreement. Likewise, each outstanding warrant to
purchase ISCG Common Stock shall convert into a warrant to purchase 77% as many
shares in FCG Common Stock at an adjusted exercise price. FCG will assume each
warrant in accordance with its terms. For example, if you have an option or
warrant to purchase 100 shares of ISCG Common Stock at an exercise price of
$7.70, after the merger you will have an option or warrant to purchase 77 shares
of FCG Common Stock, at an exercise price of $10.00. The terms and conditions
that will apply to your new option or warrant will be substantially the same as
the terms and conditions that apply to your existing option or warrant. For more
information on stock options and warrants, see "The Reorganization
Agreement-Stock Options and Warrants" beginning on page 62.
    
 
   
    Soon after the merger occurs, American Stock & Trust Company will mail to
the holders of ISCG Common Stock (1) a letter of transmittal with respect to the
surrender of valid certificates representing shares of ISCG Common Stock in
exchange for certificates representing FCG Common Stock and (2) instructions for
use of the letter of transmittal.
    
 
   
    ISCG SHAREHOLDERS SHOULD NOT SURRENDER THEIR ISCG STOCK CERTIFICATES UNTIL
THEY RECEIVE A LETTER OF TRANSMITTAL.  For more information on exchanging ISCG
shares, see "The Reorganization Agreement--Conversion of Shares; Procedures for
Exchange of Certificates" beginning on page 63.
    
 
   
Ownership of FCG Following the Merger
    
 
   
    Based upon the number of shares of ISCG Common Stock issued and outstanding
on the Record Date (which excludes outstanding options, warrants or other rights
to purchase ISCG Common Stock), an aggregate of approximately [        ]shares
of FCG Common Stock will be issued in connection with the merger. Based upon the
number of shares of FCG Common Stock issued and outstanding on the Record Date
(which excludes outstanding options or other rights to purchase FCG Common
Stock), and the number of additional shares of FCG Common Stock that will be
issued in connection with the merger, the former holders of ISCG Common Stock
will hold approximately [    ]% of the total number of shares of FCG Common
Stock issued and outstanding after consummation of the merger.
    
 
   
    Based on the number of outstanding options to purchase ISCG Common Stock as
of the Record Date, the total number of outstanding options to purchase ISCG
Common Stock will become rights to purchase an aggregate of [  ] shares of FCG
Common Stock in connection with the merger. Based on the number of outstanding
warrants to purchase ISCG Common Stock on the Record Date, the total number of
outstanding warrants to purchase ISCG Common Stock will become rights to
purchase an aggregate of [  ] shares of FCG Common Stock in connection with the
merger.
    
 
   
Material Federal Income Tax Consequences
    
 
   
    We intend that the merger be treated as a tax-free reorganization for
federal income tax purposes. ISCG shareholders should not recognize gain or loss
in the merger (other than taxes on cash received for a fraction of a share which
will be subject to tax). The merger agreement does not require the parties to
obtain a ruling from the IRS as to the tax consequences of the merger. As a
condition to the closing of the merger, each of ISCG and FCG must receive
opinions from its legal counsel that, based on certain assumptions and
certifications, the merger will be treated as a tax-free reorganization for
federal income tax purposes. For more information, see "Approval of the Merger
and Related Transactions--Material Federal Income Tax Consequences" beginning on
page 56.
    
 
   
    TAX MATTERS ARE VERY COMPLICATED. THE TAX CONSEQUENCES OF THE MERGER TO YOU
WILL DEPEND ON THE FACTS OF YOUR OWN SITUATION. WE URGE ISCG SHAREHOLDERS TO
CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE
MERGER, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX
CONSEQUENCES.
    
 
   
Opinions of Financial Advisors
    
 
   
    In deciding to approve the merger, each Board of Directors considered the
opinion of its financial advisor. FCG received an opinion from its financial
advisor, Hambrecht & Quist LLC ("Hambrecht & Quist"), that the Exchange Ratio
was fair to FCG from a financial point of view. ISCG received an opinion from
its financial advisor, Robert W. Baird & Co. Incorporated ("Baird"), that the
Exchange Ratio was fair from a financial point of view, to the holders of ISCG
Common Stock (other than FCG and
    
 
                                       6

its affiliates). More information on these opinions is provided in the following
sections of this document: "Approval of the Merger and Related
Transactions--Opinion of Financial Advisor to FCG" beginning on page 50 and
"--Opinion of Financial Advisor to ISCG" beginning on page 45. These opinions
are attached as Appendices B-1 and B-2 to this document. We encourage you to
read these opinions carefully and in their entirety.
    
 
   
Interests of Certain Persons in the Merger
    
 
   
    ISCG's shareholders should note that certain members of ISCG's management
and the ISCG Board of Directors have interests in the merger as employees and/or
directors that are different from, or in addition to, your interest as a
shareholder. If the merger is completed, certain indemnification arrangements
for persons serving as directors and officers of ISCG at the time of the merger
will be continued for at least six years after the merger is consummated. Also,
the combined company will maintain a policy of directors' and officers'
liability insurance for the benefit of those persons for three years after the
merger. In addition, FCG has agreed to use reasonable efforts to nominate and
appoint (1) Warren V. Musser, or another person designated by ISCG, to Class I
of the FCG Board of Directors to serve until the annual meeting of stockholders
to be held in 1999 and (2) David S. Lipson, or another person designated by
ISCG, to Class II of the FCG Board of Directors to serve until the annual
meeting of stockholders to be held in 2000. For more information, see "Approval
of the Merger and Related Transactions--Interests of Certain Persons in the
Merger" beginning on page 53.
    
 
   
Conditions to the Merger
    
 
   
    FCG will complete the merger only if a number of conditions are either
satisfied or waived by FCG, some of which include:

      agreement (subject to certain materiality limitations) are

    For more information on the conditions to the merger, see "The
Reorganization Agreement--Conditions to the Merger."
    
 
   
Termination of the Reorganization Agreement
    
 
   
    The Board of Directors of both companies can jointly agree to terminate the
merger agreement at any time without completing the merger. Either company can
terminate the merger agreement if:
    
 
   
    1.  we do not complete the merger by January 31, 1999;
    
 
   
    2.  a governmental authority or other legal action permanently prohibits the
        merger;
    
 
   
    3.  the ISCG shareholders do not approve the merger or the FCG stockholders
        do not approve the issuance of FCG Common Stock to ISCG shareholders in
        the merger; or
    
 
   
    4.  the other party's representations and warranties shall be or have become
        materially inaccurate or the other party breaches or materially fails to
        comply with its obligations under the merger agreement, resulting in the
        inability to satisfy a condition to the completion of the merger.
    
 
   
    In addition, FCG can terminate the merger agreement if certain "Triggering
Events" (as defined in the merger agreement) occur at any time prior to the
adoption and approval of the merger agreement and approval of the merger by the
ISCG shareholders. For more information on the circumstances under which the
merger can be terminated, see "The Reorganization Agreement--Termination"
beginning on page 72.
    
 
   
Expenses and Termination Fees
    
 
   
    We have agreed that we will each pay our own fees and expenses in connection
with the merger, whether or not the merger is consummated, except that we will
share equally all fees and expenses (other than attorneys' fees) in connection
with the printing and filing of this document and the registration statement of
which this document is a part. ISCG has agreed that if the merger agreement is
terminated under certain circumstances, it will pay to FCG a non-refundable fee
equal to $5,000,000. For more information, see "The Reorganization
Agreement--Expenses and Termination Fees" beginning on page 73.
    
 
   
Affiliate Agreements
    
 
   
    ISCG has delivered to FCG executed affiliate agreements with certain
individuals who might be considered affiliates of ISCG under the securities
laws. These agreements restrict such individuals' ability to: (1) dispose of FCG
Common Stock received in the merger and (2) dispose of ISCG Common Stock held
prior to the consummation of the merger. The purpose of these agreements is to:
(1) comply with the requirements of certain federal securities laws and (2) help
ensure that the merger will be treated as a pooling of interests for accounting
and financial reporting purposes. A form of these affiliate agreements is
included as Appendix D-1 to this document. For more information on these
agreements, see "Approval of the Merger and Related Transactions--Affiliate
Agreements" and "--Resale of FCG Common Stock" beginning on page 54.

on page 54.
    
 
   
Registration Rights Agreement
    
 
   
    FCG has agreed to enter into a registration rights agreement, when the
merger is consummated, with David S. Lipson, Technology Leaders II, Safeguard
Scientifics, Inc. and the Warrant and Stock Trust. Under these agreements, these
persons or entities will have certain rights relating to the registration under
the Securities Act of the shares of FCG Common Stock they receive in the merger.
These rights include (1) the right to notification if FCG proposes to register
any of its securities under the Securities Act in an underwritten public
offering, and, subject to certain conditions and limitations, the right to
include their shares of stock in such registration, and (2) subject to certain
conditions and limitations, the right to require FCG to file a registration
statement under the Securities Act with respect to their shares of FCG Common
Stock. The form of the registration rights agreement is included as Appendix E
to this document. For more information on this agreement and these rights, see
"Approval of the Merger and Related Transactions--Registration Rights Agreement"
beginning on page 55.
    
 
   
Anticipated Accounting Treatment
    
 
   
    We expect the merger will be accounted for as a pooling of interests, which
means that we will treat our companies as if they had always been combined for
accounting and financial reporting purposes. For more information, see "Approval
of the Merger and Related Transactions--Anticipated Accounting Treatment"
beginning on page 58.
    
 
   
Regulatory Approvals
    
 
   
    We are not required to notify the Federal Trade Commission (FTC) or the
Antitrust Division of the United States Department of Justice before we can
complete the merger. However, the FTC or the Antitrust Division has the
authority to challenge the merger on antitrust grounds before or after the
merger is completed. For more information, see "Approval of the Merger and
Related Transactions--Regulatory Matters" beginning on page 58.
    
 
   
Rights of Dissenting Shareholders of ISCG
    
 
   
    ISCG is organized under Pennsylvania law. ISCG shareholders who (1) notify
ISCG of their intent to exercise dissenters' rights, (2) effect no change in
their ownership in ISCG and (3) refrain from voting in favor of the merger will
be entitled to dissenters' rights in connection with the merger and receive the
fair value of their shares of ISCG Common Stock in cash. For a more detailed
description of the procedures ISCG shareholders must follow to properly exercise
their dissenters' rights, see "Approval of the Merger and Related
Transactions--Rights of Dissenting Shareholders of ISCG" beginning on page 57.
THE FULL TEXT OF THE REQUIREMENTS OF PENNSYLVANIA LAW TO EXERCISE DISSENTERS'
RIGHTS IS ATTACHED AS APPENDIX F TO THIS DOCUMENT AND SHOULD BE READ CAREFULLY
AND IN ITS ENTIRETY.
    
 
   
    FCG is organized under Delaware law. Under Delaware law, FCG stockholders
are not entitled to appraisal rights in connection with the merger.
    
 
   
Forward-Looking Statements May Prove Inaccurate
    
 
   
    We have each made forward-looking statement in this document (and in the
documents that are incorporated by reference) that are subject to risks and
uncertainties. Forward-looking statements include the information concerning
possible or assumed future results of operations of FCG, ISCG or the combined
company. Also, when we use such words as "believes," "expects," "anticipates" or
similar expressions, we are making forward-looking statements. You should note
that the merger and an investment in securities of FCG involve certain risks and
uncertainties that could affect the future financial results of FCG. Some of
these risks include: risks related to the integration of FCG and ISCG, risks
associated with a fixed Exchange Ratio, risks relating to the respective
businesses of FCG and ISCG and other risks and uncertainties discussed under
"Risk Factors" and elsewhere in this document and in the documents

     UNAUDITED SELECTED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION
 
   
    The unaudited selected pro forma combined condensed financial information
set forth below gives effect to the merger as a pooling of interests, assuming
that 0.77 of a share of FCG Common Stock is issued in exchange for each share of
ISCG Common Stock. The unaudited pro forma combined condensed statements of
operations for each of the years in the three-year period ended December 31,
1997 and for the six-month periods ended June 30, 1998 and 1997, combine the
historical consolidated statements of operations of FCG and ISCG as if the
merger had occurred at the beginning of the earliest period presented. The
unaudited pro forma combined condensed balance sheet as of June 30, 1998 gives
effect to the merger as if it had occurred on June 30, 1998, and combines the
historical unaudited consolidated balance sheet of FCG and the historical
unaudited consolidated balance sheet of ISCG as of such date. This data should
be read in conjunction with the selected historical consolidated financial
information, the unaudited pro forma combined condensed financial statements and
the separate historical consolidated financial statements of FCG and ISCG and
the notes thereto incorporated or included elsewhere in this Joint Proxy
Statement/Prospectus. The unaudited pro forma combined condensed financial
statements, presented for illustrative purposes only, are not necessarily
indicative of the operating results or financial position that would have been
achieved had the merger been consummated at the beginning of the earliest period
presented and should not be construed as representative of future operations.

                     COMPARATIVE PER SHARE DATA (UNAUDITED)
 
   
    The following table sets forth certain historical per share data of FCG and
ISCG and combined per share data on an unaudited pro forma basis after giving
effect to the merger as a pooling of interests at the Exchange Ratio. This data
should be read in conjunction with the selected historical consolidated
financial information and the unaudited selected pro forma combined condensed
financial information of FCG and ISCG and notes thereto, included elsewhere in
this Joint Proxy Statement/Prospectus. The unaudited pro forma combined per
share data are not necessarily indicative of the operating results or financial
position that would have occurred if the merger had been consummated at the
beginning of the periods presented, nor is it necessarily indicative of future
operating results or financial position.

(1) FCG and ISCG estimate they will incur direct transaction costs of
    approximately $3.5 million associated with the merger, which will be charged
    to operations upon consummation of the merger. The pro forma combined book
    value per share data gives effect to the estimated direct transaction costs
    as if such costs had been incurred as of the respective balance sheet date.
    The pro forma combined book value per share data does not include additional
    costs, which costs are not currently estimable, expected to be incurred
    relating to integrating the companies. The direct transaction costs are not
    included in the pro forma combined net income per share data. See "Unaudited
    Pro Forma Combined Condensed Financial Statements" and accompanying notes
    thereto.
    
 
   
(2) The historical book value per share is computed by dividing stockholders'
    equity by the number of shares of Common Stock outstanding at the end of
    each period. The pro forma combined book value per share is computed by
    dividing pro forma stockholders' equity by the pro forma number of shares of
    Common Stock outstanding as of June 30, 1998.
    
 
(3) The ISCG equivalent pro forma combined net income per share amounts are
    calculated by multiplying the FCG combined pro forma net income per share
    amounts by the Exchange Ratio of 0.77.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
 
FINANCIAL STATEMENTS
 
   
    The following unaudited pro forma combined condensed financial statements
have been prepared to give effect to the merger, using the pooling of interests
method of accounting. These financial statements reflect certain assumptions
deemed probable by management regarding the merger (e.g., that share information
used in the unaudited pro forma information approximates actual share
information at the effective date). No adjustments to the unaudited pro forma
combined condensed financial statements have been made to account for different
possible results in connection with the foregoing, as management believes that
the impact on such information of varying outcomes, individually or in the
aggregate, would not be material.
    
 
   
    The unaudited pro forma combined condensed balance sheet as of June 30, 1998
gives effect to the merger as if it had occurred on June 30, 1998, and combines
the historical unaudited consolidated balance sheet of FCG and the historical
unaudited consolidated balance sheet of ISCG as of such date.
    
 
   
    The unaudited pro forma combined condensed statements of operations for each
of the years in the three-year period ended December 31, 1997 and for the
six-month period ended June 30, 1998, combine the historical consolidated
statements of operations of FCG and ISCG as if the merger had occurred at the
beginning of the earliest period presented.
    
 
   
    FCG and ISCG estimate that they will incur direct transaction costs of
approximately $3.5 million associated with the merger, which will be charged to
operations upon consummation of the merger. In addition, it is expected that
following the merger, the combined company will incur additional costs, which
can not currently be estimated, associated with integrating the operations of
the two companies. Integration-related costs are not included in the
accompanying unaudited pro forma combined condensed financial statements.
    
 
   
    Unaudited pro forma combined condensed financial information is presented
for illustrative purposes only and is not necessarily indicative of the
financial position or results of operations that would have actually been
reported had the merger occurred at the beginning of the earliest period
presented, nor is it necessarily indicative of future financial position or
results of operations. These unaudited pro forma combined condensed financial
statements are based upon the respective historical consolidated financial
statements of FCG and ISCG and notes thereto, included or incorporated by
reference elsewhere in this Joint Proxy Statement/Prospectus. These unaudited
pro forma combined condensed financial statements do not incorporate, nor do
they assume, any benefits from cost savings or synergies of operations of the
combined company.

                          NOTES TO UNAUDITED PRO FORMA
                    COMBINED CONDENSED FINANCIAL STATEMENTS
 
NOTE 1--PERIODS COMBINED
 
    The FCG consolidated balance sheet as of June 30, 1998 has been combined
with the ISCG consolidated balance sheet as of June 30, 1998. The FCG
consolidated statements of operations for the six months ended June 30, 1998 and
1997 and for the years ended December 31, 1997, 1996 and 1995 have been combined
with the ISCG consolidated statements of operations for the six months ended
June 30, 1998 and 1997, and for the years ended December 31, 1997, 1996, and
1995 respectively.
 
NOTE 2--MERGER COSTS
 
   
    FCG and ISCG estimate they will incur direct transaction costs of
approximately $3.5 million associated with the merger, consisting primarily of
fees for investment banking, filings with regulatory agencies, legal,
accounting, financial printing and other related costs. These nonrecurring costs
will be charged to operations in the fiscal quarter in which the merger is
consummated. The unaudited pro forma combined balance sheet gives effect to such
charges as if they had been incurred as of June 30, 1998, but the effects of
these costs have not been reflected in the unaudited pro forma combined
statements of operations as they are nonrecurring in nature. It is expected that
substantially all of the costs will be paid out of existing cash reserves within
six to twelve months after the consummation of the merger.
    
 
NOTE 3--PRO FORMA NET INCOME PER SHARE
 
    The unaudited pro forma combined net income per common and equivalent share
is based upon the weighted average number of common and equivalent shares of FCG
and ISCG outstanding for each period at the Exchange Ratio.
 
NOTE 4--PRO FORMA NET INCOME (LOSS) PER SHARE
 
    The following table reconciles the number of shares used in the pro forma
earnings per share computations to the numbers set forth in FCG's and ISCG's
historical statements of operations (in thousands, except the Exchange Ratio and
per share amounts):

                                  RISK FACTORS
    
 
   
    THIS JOINT PROXY STATEMENT/PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS
THAT INVOLVE KNOWN AND UNKNOWN RISKS AND UNCERTAINTIES. THE ACTUAL RESULTS OF
THE COMBINED COMPANY MAY DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE
FORWARD-LOOKING STATEMENTS. YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED
BELOW, ELSEWHERE IN THIS DOCUMENT, AND IN THE DOCUMENTS INCORPORATED HEREIN BY
REFERENCE IN MAKING AN INVESTMENT DECISION. KEEP IN MIND THAT THE RISKS
DESCRIBED BELOW ARE NOT THE ONLY RISKS FACING FCG, ISCG OR THE COMBINED COMPANY.
    
 
   
RISKS RELATING TO THE MERGER
    
 
   
    INTEGRATION RISKS.  Integrating FCG and ISCG will be a complex,
time-consuming and expensive process. Before the merger, FCG and ISCG operated
independently, each with its own business, business culture, clients, employees
and systems. After the merger, FCG and ISCG must operate as a combined
organization utilizing common (1) information and communication systems, (2)
operating procedures, (3) financial controls and (4) human resource practices,
including benefit, training and professional development programs. There may be
substantial difficulties, costs and delays involved in integrating FCG and ISCG.
These may include:
    
 
   
    - Distracting management from the business of the combined company
    
 
   
    - Potential incompatibility of business cultures
    
 
   
    - Perceived adverse change in client service standards, business focus,
      billing practices, or service offerings available to clients
    
 
   
    - Perceived uncertainty in career opportunities, benefits and the long-term
      value of stock options available to employees
    
 
   
    - Costs and delays in implementing common systems and procedures
    
 
   
    - Potential inefficiencies in delivering services to the clients of the
      combined company
    
 
   
    - Potential inability to obtain consents of third parties required because
      of the merger
    
 
   
    Any one or all of these factors may cause increased operating costs, lower
than anticipated financial performance or the loss of clients and employees.
Many of these factors are also outside the control of either company. The
failure to the integrate FCG and ISCG would have a material adverse effect on
the business, financial condition and results of operations of the combined
company.
    
 
   
    RISKS ASSOCIATED WITH FIXED EXCHANGE RATIO.  At the effective time of the
merger, each outstanding share of ISCG Common Stock will be converted into a
fixed number of shares of FCG Common Stock. The number of shares of FCG Common
Stock received in the merger will not increase or decrease due to fluctuations
in the market price of either company's stock. Recent market prices of FCG
Common Stock and ISCG Common Stock are set forth under the captions
"Summary--Markets and Market Prices" beginning on page 10 and "Comparative Per
Share Market Price Data and Dividend Policy" beginning on page 38. We encourage
ISCG shareholders to obtain current market quotations for FCG Common Stock and
ISCG Common Stock. FCG Common Stock and ISCG Common Stock have been subject to
price volatility. The market prices of FCG Common Stock and ISCG Common Stock
cannot be guaranteed or predicted. For more information, see "Comparative Per
Share Market Price Data and Dividend Policy" beginning on page 38.
    
 
   
    RIGHTS OF HOLDERS OF ISCG COMMON STOCK FOLLOWING THE MERGER.  Following the
Merger, ISCG shareholders will become FCG stockholders. There are important
differences between the rights of shareholders of ISCG and the rights of
stockholders of FCG. For a description of these differences, see "Comparison of
Shareholders' Rights."
    
 
                                       24
<PAGE>
   
RISKS RELATING TO THE BUSINESS OF FCG
    
 
   
    POTENTIAL INABILITY TO ATTRACT AND RETAIN EMPLOYEES.  FCG's business is
labor-intensive and requires highly skilled employees. Most of FCG's consultants
possess extensive expertise in healthcare, information technology and consulting
fields. To serve a growing client base, FCG must continue to recruit and retain
qualified personnel with expertise in each of these three fields. Competition
for such personnel is intense. FCG competes for such personnel with management
consulting firms, healthcare organizations, software firms and other businesses.
Many of these entities have substantially greater financial and other resources
than FCG. FCG may not be able to recruit and retain a sufficient number of
qualified personnel to serve existing and new clients. If FCG fails to to
recruit and retain a sufficient number of qualified personnel, FCG's ability to
expand its client base or services could be impaired and FCG's business,
financial condition and results of operations could be adversely effected.
    
 
   
    RISKS OF EMPLOYEE TURNOVER.  FCG has experienced employee turnover rates at
or above industry averages as a result of (1) dependence on lateral hiring of
consultants, (2) travel demands imposed on its consultants, and (3) loss of
employees to competitors and clients. Continued or increased employee turnover
could materially adversely effect FCG's business, financial condition and
results of operations. In addition, many of FCG's consultants develop strong
business relationships with FCG's clients. FCG depends on these relationships to
generate additional assignments and engagements. Losing one or more consultants
could erode FCG's client base and decrease FCG's revenue.
    
 
   
    FLUCTUATIONS IN OPERATING RESULTS.  FCG's net revenue and operating results
may fluctuate significantly because of a number of factors, many of which are
outside FCG's control. These factors may include:
    
 
   
    - Losing key personnel and other employees
    
 
   
    - Losing one or more significant clients
    
 
   
    - Consummating an acquisition
    
 
   
    - Costs of integrating acquired operations
    
 
   
    - Timing and collection of payments and new client engagements
    
 
   
    - Delays in securing and completing client engagements
    
 
   
    - Fluctuations in market demand for FCG's services, consultant hiring and
      utilization
    
 
   
    - Variability in the number of billable days
    
 
   
    - Availability of foreign net operating losses and other credits against
      FCG's earnings
    
 
   
    - Increased competition and pricing pressures
    
 
   
    - Changes in business strategy, pricing and billing policies of FCG and its
      competitors
    
 
   
    - International currency fluctuations
    
 
   
    A substantial portion of FCG's expenses, particularly personnel and related
costs, depreciation, office rent and occupancy costs, are relatively fixed. One
or more of the foregoing factors may cause FCG's operating expenses to be
disproportionately high during any given period. In addition, FCG bills certain
of its services on a fixed-price basis, and any assignment delays or
expenditures of time beyond that projected for the assignment could result in
write-offs of client billings. Significant write-offs could materially adversely
effect FCG's business, financial condition and results of operations. Based on
the preceding factors, FCG may experience a shortfall in revenue or earnings or
otherwise fail to meet public market expectations, which could materially
adversely effect FCG's business, financial condition and the market price of the
FCG Common Stock.
    
 
                                       25
<PAGE>
   
    VARIABILITY IN THE NUMBER OF BILLABLE DAYS.  FCG's net revenue and operating
expenses vary depending on the number of billable days in any given quarter. FCG
typically has a lower number of billable days in the second and fourth quarters
of every year. In the second quarter of each year, FCG requires employee
attendance at an annual meeting of all of its employees. In the fourth quarter
of each year, FCG also encourages its employees to take vacation during the
December holidays. The number of billable days may also vary as a result of
vacation days, sick time, paid and unpaid leave and other holidays.
    
 
   
    RISKS OF UNPREDICTABLE ENGAGEMENT CYCLES.  The timing of client engagements
and service fulfillment is not predictable with any degree of accuracy. You
should not rely on prior engagement cycles as any indication of the timing of
future client engagements or revenues.
    
 
   
    Prior to client engagements, FCG typically spends a substantial amount of
time and resources (1) identifying strategic or business issues facing the
client, (2) defining engagement objectives, (3) gathering information, (4)
preparing proposals and (5) negotiating contracts. FCG may be required to hire
new consultants before securing a client engagement. Clients may defer commiting
to new assignments for any length of time and for any reason. Such deferrals
could require FCG to maintain a significant number of under-utilized consultants
during any given period. In addition, failing to procure an engagement after
spending such time and resources could materially adversely effect FCG's
business, financial condition and results of operations.
    
 
   
    The length of time required to complete an assignment often depends on
factors outside FCG's control, including:
    
 
   
    - Existing information systems at the client site
    
 
   
    - Changes or the anticipation of changes in the regulatory environment
      affecting healthcare organizations
    
 
   
    - Budgetary cycles and constraints
    
 
   
    - Availability of personnel and other resources
    
 
   
    - Consolidation in the healthcare industry
    
 
   
    FCG may be unable to satisfy objectives and complete projects and services.
Any such failure may result in write-offs of client billings, reduction in
engagements or loss of clients. FCG's failure to deliver the services required
by the client on a timely basis or within anticipated budgets could materially
adversely affect FCG's business, financial condition and results of operations.
    
 
   
    DEPENDENCE ON EXISTING CLIENTS.  FCG's success depends on obtaining
additional engagements from its existing clients. A substantial portion of FCG's
revenues are derived from services provided to its existing clients. The loss of
a small number of clients may result in a material decline in revenues and cause
FCG to fail to meet public market expectations of its financial performance and
operating results. Any material failure on the part of FCG to generate
additional revenues from its existing clients may materially adversely effect
FCG's business, financial condition and results of operations.
    
 
   
    POTENTIAL INABILITY TO MANAGE GROWTH.  FCG's business has grown rapidly in
recent years. This growth has placed new and increased demands on FCG's vice
presidents and other management personnel. This growth has also placed
significant and increasing demands on FCG's financial, technical and operational
resources and on its information systems. To manage any future growth, FCG must
(1) extend its financial reporting and information management systems to a
growing number of offices and employees, and (2) develop and implement new
procedures and controls to accommodate new operations, services and clients.
Increasing operational and administrative demands may make it difficult for
FCG's vice presidents to engage in business development activities. Adding a
significant number of new employees and offices may also impair FCG's ability to
maintain its service delivery standards and corporate culture. In addition, FCG
has in the past changed, and may in the future change, its organizational
structure and business
    
 
                                       26
<PAGE>
   
strategy. Such changes may result in operational inefficiencies and delays in
delivering FCG's services. Such changes could also cause a disruption in FCG's
business and could have a material adverse effect on FCG's business, financial
condition and results of operations. If FCG fails to effectively manage its
growth, FCG's business, financial condition and results of operations could be
adversely affected.
    
 
   
    RISKS ASSOCIATED WITH ACQUISITIONS.  FCG intends to grow, in part, by
acquiring complementary professional practices within the healthcare industry.
In 1998, FCG completed two acquisitions and is in the process of completing a
third acquisition. Integrating acquired operations is a complex, time-consuming
and expensive process. All acquisitions involve risks that could materially and
adversely effect FCG's business and operating results. These risks include (1)
distracting management from the business of FCG, (2) losing key personnel and
other employees, (3) losing clients, (4) costs, delays and inefficiencies
associated with integrating acquired operations and personnel, and (5)
amortizing the cost of acquired assets and goodwill. Acquired businesses may not
enhance FCG's services, provide FCG with increased client opportunities or
result in growth. Combining acquired operations with FCG may result in lower
overall operating margins, greater stock price volatility and quarterly earnings
fluctuations. Cultural incompatibilities, career uncertainties and other factors
associated with such acquisitions may result in the loss of employees and
clients. Failing to acquire and successfully integrate complementary practices
could materially adversely effect FCG's business, financial condition and
results of operations.
    
 
   
    RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS.  FCG provides its services
to international clients. Expanding into international markets will require FCG
to (1) spend a significant amount of management, human and financial resources,
(2) hire additional personnel, and (3) establish international offices. FCG may
be unable to recruit and retain a sufficient number of qualified consultants in
each country in which it intends to conduct its business. If FCG fails to
recruit and retain qualified employees, FCG's ability to expand internationally
may be impaired and FCG's business, financial condition and results of
operations could be adversely effected. FCG's international operations are
subject to a variety of risks, including:
    
 
   
    - Difficulties and costs of localizing services in international markets
    
 
   
    - Unfavorable pricing and price competition
    
 
   
    - Currency fluctuations
    
 
   
    - Longer payment cycles in some countries
    
 
   
    - Difficulties in collecting international accounts receivable
    
 
   
    - Difficulties in enforcing contractual obligations and intellectual
      property rights
    
 
   
    - Adverse tax consequences
    
 
   
    - Increased costs associated with maintaining international marketing
      efforts and offices
    
 
   
    - Adverse changes in regulatory requirements
    
 
   
    - Economic instability
    
 
   
    Any one or all of these factors may cause increased operating costs, lower
than anticipated financial performance and may materially adversely effect FCG's
business, financial condition and results of operations.
    
 
   
    IMPACT OF YEAR 2000.  Many existing computer programs and systems, including
those used by FCG's clients, use only two digits to identify the year in the
date field. These programs may be unable to process date/time information
between the twentieth and twenty-first centuries. This inability could cause the
disruption or failure of such computer systems (the "Y2K Problem"). Solving the
Y2K Problem will require a large amount of time and resources. FCG's clients may
have to reallocate a significant portion of their budgets away from FCG's
services to address this problem. Such reallocation would have a material
    
 
                                       27
<PAGE>
   
adverse effect on FCG's business, financial condition and results of operations.
FCG's current time and billing systems are not Y2K compliant. FCG has purchased
an upgrade to these systems that will render them Y2K compliant. FCG expects to
complete deployment of this upgrade in the fourth quarter of 1998. There can be
no assurance that such deployment will begin as planned or, if begun, will be
completed in a timely and cost-effective manner.
    
 
   
    DEPENDENCE ON KEY EMPLOYEES.  FCG's performance depends on the continued
service of its senior management and certain other key employees. The loss of
the services of these employees could result in disruption of FCG's business,
stock price volatility and could have a material adverse effect on FCG's
business, financial condition and results of operations. FCG has not entered
into long-term employment contracts with any of its employees and does not
maintain key employee life insurance.
    
 
   
    RISKS IN CLIENT ENGAGEMENTS.  FCG's services often involve complex
information systems and software which are critical to the clients' operations.
FCG's failure to meet client expectations in the performance of its services may
damage FCG's reputation in the healthcare industry and adversely affect its
ability to attract and retain clients. If a client is not satisfied with FCG's
services, FCG will generally spend additional human and other resources at its
own expense to ensure client satisfaction. Such expenditures will typically
result in a lower margin on such engagements and could materially adversely
effect FCG's business, financial condition and results of operations.
    
 
   
    In the course of providing its services, FCG will often recommend the use of
other software and hardware products. These products may not perform as expected
or contain defects. If this occurs, FCG's reputation could be damaged and it
could be subject to liability. FCG attempts to limit its exposure to potential
liability claims. Such limitations may not be effective. A successful liability
claim brought against FCG may adversely affect FCG's reputation in the
healthcare industry and could have a material adverse effect on FCG's business,
financial condition and results of operations. Although FCG maintains liability
insurance, such insurance may not provide adequate coverage for successful
claims against FCG.
    
 
   
    COMPETITION IN THE HEALTHCARE INFORMATION SERVICES INDUSTRY.  The market for
healthcare information technology consulting is very competitive. FCG has
competitors that provide some or all of the services provided by FCG. In
strategic consulting services, FCG competes with (1) international consulting
firms, (2) regional and specialty consulting firms and (3) the consulting groups
of international accounting firms such as KPMG Peat Marwick LLP, Ernst & Young
LLP, Deloitte & Touche LLP, PricewaterhouseCoopers, LLP and Andersen Consulting.
In implementation and integration services, FCG competes with (1) information
system vendors such as HBO & Company, Inc., Shared Medical Systems Corporation
and Integrated Systems Solution Corporation, a division of International
Business Machines Corporation; (2) service groups of computer equipment
companies; (3) systems integration companies such as Electronic Data Systems
Corporation, Perot Systems Corporation, CAP Gemini America, Inc. and Computer
Sciences Corporation; (4) clients' internal information management departments;
and (5) other healthcare consulting firms such as DAOU Systems Inc. and Superior
Consultant Holdings Corporation.
    
 
   
    Many of FCG's competitors have significantly greater financial, human and
marketing resources than FCG. Such competitors may be able to respond more
quickly to new or emerging technologies and changes in customer demands, or to
devote greater resources to the development, promotion, sale and support of
their products and services than FCG. FCG may be unable to compete effectively
with current and future competitors. Competitive pressures may cause FCG's
revenue or operating margins to decline or otherwise materially adversely effect
its business, financial condition and results of operations.
    
 
   
    RISKS OF REGULATORY AND TECHNOLOGICAL CHANGE.  The healthcare industry is
subject to regulatory and technological changes that may affect the procurement
practices and operations of healthcare organizations. During the past several
years, the healthcare industry has been subject to an increase in governmental
regulation and reform proposals. These reforms could increase governmental
involvement in the
    
 
                                       28
<PAGE>
   
healthcare industry, lower reimbursement rates or otherwise change the operating
environment of FCG's clients. Healthcare organizations may react to these
proposals by curtailing or deferring investments, including those for FCG's
services. FCG cannot predict with any certainty what impact, if any, such
legislative reforms could have on its business.
    
 
   
    Technological change in the network and application markets has created high
demand for consulting, implementation and integration services. If the pace of
technological change were to diminish, FCG could experience a decrease in demand
for its services. Any material decrease in demand would materially adversely
effect FCG's business, financial condition and results of operations.
    
 
   
    RISKS ASSOCIATED WITH CONSOLIDATION IN THE HEALTHCARE INDUSTRY.  FCG derives
substantially all of its revenue from clients in the healthcare industry. As a
result, FCG's business, financial condition and results of operations are
influenced by conditions affecting this industry, particularly current trends
towards consolidation among healthcare organizations. Such consolidation may
reduce the number of existing and potential clients for FCG's services. In
addition, the resulting organizations could have greater bargaining power, which
could erode the current pricing structure for FCG's services. The reduction in
the size of FCG's target market or the failure of FCG to maintain its pricing
strategies could have a material adverse effect on FCG's business, financial
condition and results of operations.
    
 
   
    LIMITED PROTECTION OF PROPRIETARY INFORMATION AND PROCEDURES.  FCG must
protect its proprietary information, including its proprietary methodologies,
research, tools, software code and other information. To do this, FCG relies on
a combination of copyright and trade secret laws and confidentiality procedures
to protect its intellectual property. These steps may not protect FCG's
proprietary information. In addition, the laws of certain countries do not
protect or enforce proprietary rights to the same extent as do the laws of the
United States. FCG is currently providing its services to clients in
international markets. FCG's proprietary information may not be protected to the
same extent as provided under the laws of the United States, if at all. The
unauthorized use of FCG's intellectual property could have a material adverse
effect on FCG's business, financial condition or results of operations. In
addition, third parties may assert infringement claims against FCG in the
future. Such claims may result in protracted and costly litigation, regardless
of the merits of such claims.
    
 
   
    CONTROL BY EXISTING STOCKHOLDERS AND MANAGEMENT.  Upon consummation of the
Merger, FCG's existing stockholders will beneficially own approximately [      ]
shares, or [   ]%, of the outstanding shares of FCG Common Stock. As a result,
FCG's existing stockholders, if acting together, will be able to exercise
control over or significantly influence matters requiring stockholder approval,
including the election of directors, mergers, consolidations and sales of all or
substantially all of the assets of FCG.
    
 
   
    ANTI-TAKEOVER EFFECTS OF DELAWARE LAW AND CERTAIN CHARTER
PROVISIONS.  Certain provisions of Delaware law applicable to FCG could delay or
make more difficult a merger, tender offer or proxy contest involving FCG,
including Section 203 of the DGCL, which prohibits a Delaware corporation from
engaging in any business combination with any interested stockholder for a
period of three years from the date the person became an interested stockholder
unless certain conditions are met. In addition, the FCG Board of Directors may
issue shares of preferred stock without stockholder approval on such terms as
the FCG Board Directors may determine. The rights of the holders of FCG Common
Stock will be subject to, and may be adversely affected by, the rights of the
holders of any preferred stock that may be issued in the future. In addition,
the FCG Certificate of Incorporation and FCG Bylaws provide for a classified
board of directors, eliminate the right of stockholders to act by written
consent without a meeting, require advanced stockholder notice to nominate
directors and raise matters at the annual stockholders meeting, eliminate
cumulative voting in the election of directors and allow for the removal of
directors only for cause and with a two-thirds vote of FCG's outstanding shares.
All of the foregoing could have the effect of delaying, deferring or preventing
a change in control of FCG and could limit the price that certain investors
might be willing to pay in the future for shares of FCG Common Stock.

RISKS RELATING TO THE BUSINESS OF ISCG
    
 
   
    ISCG MAY NOT BE ABLE TO ATTRACT AND RETAIN A SUFFICIENT NUMBER OF TECHNICAL
     EMPLOYEES TO MEET ITS WORK REQUIREMENTS.
    
 
   
    ISCG's business of rendering professional services is labor-intensive. ISCG
believes its future success will depend in large part upon attracting, retaining
and motivating sufficient numbers of highly-skilled technical employees. There
are not enough information services professionals available to meet the current
demands of the computer consulting industry and ISCG believes that demand will
remain high for the foreseeable future. Therefore, in the future, ISCG might not
be able to attract and retain sufficient numbers of such highly-skilled
technical employees to meet its work requirements. The inability to attract new
technical employees or the departure of an unusually high number of ISCG's
technical employees would have a material adverse impact on ISCG's business.
    
 
   
    ISCG'S REVENUES MAY DECREASE AS A RESULT OF CERTAIN CHANGES IN THE
     PHARMACEUTICAL INDUSTRY.
    
 
   
    Historically, a significant portion of ISCG's revenues has come from
companies in the pharmaceutical business. This trend may continue in the future.
The following chart shows the approximate percentage of total revenues ISCG
derived from the pharmaceutical industry during 1995, 1996, 1997 and 1998
(through September 30, 1998).
    
 
   
<TABLE>

</TABLE>
    
 
   
    ISCG's revenues are linked to the pharmaceutical industry's research and
development expenditures. Should any of the following events occur in the
pharmaceutical industry, ISCG's business could be negatively affected in a
material way:
    
 
   
    - the industry's general economic environment changes adversely;
    
 
   
    - companies continue to consolidate; or
    
 
   
    - research and development expenditures or pharmaceutical companies'
      expenditures on technology in general decrease.
    
 
   
    A trend in the pharmaceutical industry is for companies to "outsource"
either large information technology-dependent projects or their information
systems staffing requirements. Outsourcing means that, rather than utilize its
own employees, a company contracts with a third party to undertake an entire
project or to provide technical personnel to augment their own staff. ISCG
benefits when pharmaceutical companies outsource to it. If this outsourcing
trend slows down or stops, ISCG's financial condition and results of operations
could be impacted in a materially adverse way.
    
 
                                       30
<PAGE>
   
    A FEW CLIENTS MAY ACCOUNT FOR A SIGNIFICANT PERCENTAGE OF ISCG'S REVENUES IN
     ANY GIVEN YEAR AND ISCG'S BUSINESS COULD BE NEGATIVELY IMPACTED IF IT WERE
     UNABLE TO SECURE ENGAGEMENTS FOR LARGE PROJECTS WITH SIGNIFICANT CLIENTS IN
     A PARTICULAR YEAR.
    
 
   
    A small number of clients each usually account for 10% or more of ISCG's
revenues in any given year. The following chart shows ISCG clients that
accounted for 10% or more of ISCG's revenues in 1995, 1996, 1997 and 1998
(though September 30, 1998).

</TABLE>
    
 
   
    ISCG's clients generally implement large software applications on an
irregular basis because such implementation is a complex, time-intensive and
costly process. Therefore, the amount of revenues derived by ISCG from a
specific client may vary significantly from year-to-year. Accordingly, ISCG
expects that the identity of clients accounting for large portions of its
revenues will change from year-to-year.
    
 
   
    ISCG'S FINANCIAL CONDITION COULD BE ADVERSELY AFFECTED IF ITS TECHNICAL
     EMPLOYEES ARE UNDER-UTILIZED OR IF ITS BILLING MARGINS DECREASE.
    
 
   
    ISCG's revenues are derived largely from the hourly fees its clients pay for
the professional services rendered by ISCG's technical employees. The
"utilization rate" of ISCG's technical employees is defined as the number of
hours actually billed during any given period divided by the number of hours
available during that period. Utilization rates can vary based on a number of
factors, including (1) non-billable time between assignments that is incurred by
technical employees, (2) vacation hours taken by technical employees, (3)
weather events that prevent technical employees from reaching work sites, and
(4) training of technical employees. Since virtually all of ISCG's technical
employees are full time employees and their costs are relatively fixed,
variances in utilization rates affect both ISCG's revenues and operating
results.
    
 
   
    In addition, the shortage of highly trained technical employees in the
industry has caused upward pressure on such employees' wages. ISCG's "billing
margin" is the difference between its cost of delivering consulting services
(which cost consists predominately of wages and related benefits) and the rates
ISCG charges its customers. A decrease in ISCG's billing margin would adversely
affect ISCG's financial performance. ISCG cannot guarantee that its billing
margin will not decrease in the future.
    
 
   
    ISCG HAS GROWN RAPIDLY AND CONTINUES TO GROW RAPIDLY. IF ISCG FAILS TO
     EFFECTIVELY MANAGE THIS GROWTH, ITS FINANCIAL RESULTS COULD SUFFER.
    
 
   
    From January 1, 1992 through September 30, 1998, the size of ISCG's
professional staff increased from 61 to    personnel. This growth has placed
increasing demands on ISCG's management, financial and other resources. ISCG has
built these resources and systems to account for such growth, but continued
growth may require ISCG to increase its investment in such systems, or to
reorganize its management team. Such changes, should they occur, could cause an
interruption or diversion of focus from ISCG's core business activities and have
an adverse effect on financial results.
    
 
                                       31
<PAGE>
   
    IF ISCG FAILS TO ESTABLISH AND MAINTAIN RELATIONSHIPS WITH VENDORS OF
     SOFTWARE PRODUCTS, IT COULD HAVE A NEGATIVE EFFECT ON ISCG'S ABILITY TO
     SECURE ENGAGEMENTS.
    
 
   
    ISCG has established a non-exclusive partnership arrangement with
Documentum, Inc. ("Documentum"). Documentum markets document management software
applications largely to the pharmaceutical industry. ISCG believes that its
relationship with this vendor is important to its sales, marketing and support
activities. ISCG integrates Documentum's software products into clients'
systems. If a client or prospective client selects one of Documentum's products,
ISCG may be hired to integrate the product into the client's system. ISCG's
strong relationship with Documentum has often resulted in sales leads and client
engagements for ISCG. If ISCG fails to maintain its relationship with Documentum
or fails to establish relationships with other vendors, its business could be
materially adversely effected.
    
 
   
    IF ISCG FAILS TO KEEP PACE WITH TECHNOLOGICAL DEVELOPMENTS IN THE
     INFORMATION TECHNOLOGY INDUSTRY, IT COULD HAVE A MATERIAL ADVERSE EFFECT ON
     ISCG'S BUSINESS.
    
 
   
    The information technology industry has experienced and continues to
experience rapid technological advances and developments. To continue to succeed
in the future, ISCG must develop solutions that keep pace with continuing
changes in information processing technology, evolving industry standards and
changing client preferences. ISCG may not succeed in addressing these
developments on a timely basis. If ISCG delays or fails to address these
developments, ISCG's business could be materially negatively impacted. In
addition, technologies or methodologies developed by others could make ISCG's
services noncompetitive or obsolete.
    
 
   
    IF ISCG DOES NOT EFFECTIVELY COMPETE, ITS BUSINESS WILL BE NEGATIVELY
     IMPACTED.
    
 
   
    ISCG competes in the commercial professional services segment of the
information technology industry. In this segment, many companies compete for
client assignments and for technical personnel. Many of the companies that ISCG
competes with or may compete with have significantly greater financial,
technical and marketing resources and have greater name recognition. ISCG
primarily seeks consulting, applications development and systems and networking
engagements with companies within the pharmaceutical industry. A number of other
professional services firms also seek these kinds of engagements. ISCG believes
that the following are the principal factors on which ISCG and companies
operating in the same industry segment compete:
    
 
   
    - responsiveness to client needs;
    
 
   
    - availability of technical personnel;
    
 
   
    - speed of applications development;
    
 
   
    - quality of service;
    
 
   
    - price;
    
 
   
    - project management capability;
    
 
   
    - technical expertise; and
    
 
   
    - the ability to market to and serve clients internationally.
    
 
   
    ISCG believes that its ability to compete also depends in part on the
following factors that are outside of its control:
    
 
   
    - the ability of its competitors to hire, retain and motivate qualified
      technical personnel;
    
 
   
    - the ownership by competitors of software used by potential clients;
    
 
   
    - the development of software that would reduce or eliminate the need for
      ISCG's services;
    
 
                                       32
<PAGE>
   
    - the price at which others offer comparable services; and
    
 
   
    - the extent of its competitors' responsiveness to customer needs.
    
 
   
    IF CERTAIN KEY EMPLOYEES OF ISCG LEAVE ISCG OR ARE NO LONGER ABLE TO PERFORM
     SERVICES FOR ISCG, IT COULD HAVE A MATERIAL ADVERSE EFFECT ON ISCG'S
     BUSINESS.
    
 
   
    ISCG believes that the efforts and abilities of its senior management are
very important to its continued success. In particular, if David S. Lipson,
ISCG's Chairman, Chief Executive Officer and President, or certain of ISCG's
other executive officers or senior managers left ISCG or were unable to perform
services for ISCG, it could have a material negative impact on ISCG's business.
ISCG has employment agreements with each of its executive officers.
    
 
   
    COMPUTER SYSTEMS USED BY OR DESIGNED BY ISCG OR USED BY THIRD PARTIES WITH
     WHOM ISCG REGULARLY DEALS MAY NOT BE ABLE TO PROCESS DATE/TIME INFORMATION
     BETWEEN THE TWENTIETH AND TWENTY-FIRST CENTURIES. THIS INABILITY COULD
     CAUSE THE DISRUPTION OR FAILURE OF SUCH COMPUTER SYSTEMS. ISCG'S BUSINESS
     COULD BE INTERRUPTED AND SUFFER A MATERIAL ADVERSE EFFECT AS A RESULT OF
     SUCH DISRUPTION OR FAILURE.
    
 
   
    Many existing computer programs and systems, including certain of those used
by ISCG for its own internal purposes and certain of those used by its clients,
suppliers, vendors and others, use only two digits to identify the year in the
date field. Some custom applications designed, built or modified by ISCG for its
clients may also only use two digits to identify the year in the date field.
These programs were designed and developed without considering the impact of
their inability to process date/time information between the twentieth and
twenty-first centuries. This ability to process information is described in
"Risks Relating to the Business of FCG" as "Y2K." ISCG has identified four main
areas of its Y2K risk:
    
 
   
    - ISCG's internal computer systems could be disrupted or fail, causing an
      interruption or decrease in ISCG's ability to continue its operations;
    
 
   
    - the computer systems of third parties with whom ISCG regularly deals,
      including among others its clients, suppliers, vendors, utilities,
      financial institutions, could be disrupted or fail, causing an
      interruption or decrease in ISCG's ability to continue its operations;
    
 
   
    - ISCG could be exposed to liabilities if certain of the custom applications
      designed, built or modified by ISCG for its clients are disrupted or fail
      and ISCG is obligated to fix those applications; and
    
 
   
    - ISCG's revenue could decline if clients' resources are diverted from
      ISCG's traditional work to fixing the Y2K problem.
    
 
   
    ISCG is currently evaluating the nature and extent of the Y2K issues for its
internal systems. ISCG believes that, before December 31, 1999, its material
internal systems will be substantially able to process date/time information
between the twentieth and twenty-first centuries. If ISCG does not achieve Y2K
compliance for its internal systems on a timely basis, ISCG's business could
suffer a material adverse impact.
    
 
   
    If the business of any third party with whom ISCG regularly deals, including
among others its clients, suppliers, vendors, utilities, financial institutions,
is significantly disrupted because such party is not Y2K compliant, it could
have a material adverse effect on ISCG's business. These disruptions could
include, among other things:
    
 
   
    - a client's inability to process payments to ISCG;
    
 
   
    - a financial institution's inability to process checks drawn on ISCG's bank
      accounts, accept deposits or process wire transfers;
    
 
   
    - a client's, supplier's, vendor's or financial institution's business
      failure;
    
 
                                       33
<PAGE>
   
    - an interruption in deliveries of computer equipment and other supplies
      from vendors;
    
 
   
    - a loss of voice and data connections ISCG uses to share information;
    
 
   
    - a loss of electric power to ISCG's facilities; and
    
 
   
    - other interruptions to the normal conduct of business by ISCG, the nature
      and extent of which ISCG cannot foresee.
    
 
   
    ISCG does not know whether any of the disruptions described above will
actually occur, or if they do occur, the effect they will have on ISCG.
    
 
   
    ISCG is currently evaluating the extent to which applications that ISCG has
built, designed or modified for its clients may not be able to process date/time
information between the twentieth and twenty-first centuries. ISCG is also
considering its obligations, if any, to make these applications Y2K compliant.
ISCG's Y2K analyses may not be completed on a timely basis and the costs and
liabilities associated with the Y2K issue may materially adversely impact ISCG's
business.
    
 
   
    ISCG'S QUARTERLY RESULTS MAY VARY AS A RESULT OF UNDER-UTILIZATION OF
     TECHNICAL EMPLOYEES AND/OR THE TIMING OF CERTAIN GENERAL AND ADMINISTRATIVE
     SPENDING.
    
 
   
    ISCG's business is generally not seasonal. However, since its
employee-related costs are relatively fixed and revenues fluctuate,
profitability may vary from one quarter to another. The following factors
contribute to such variations:
    
 
   
    - changes in employee utilization rates;
    
 
   
    - the timing of certain general and administrative expenses;
    
 
   
    - the timing of new hires,
    
 
   
    - the timing of training for new and existing technical employees; and
    
 
   
    - the number of business days in a particular quarter.
    
 
   
    These factors could impact ISCG's future quarterly results. Therefore, the
future amount or pattern of ISCG's quarterly results will not necessary be the
same as its historical amount or pattern of quarterly results.

                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS
 
BACKGROUND OF THE MERGER
 
    Beginning in 1997, FCG's Board of Directors (the "FCG Board") evaluated
FCG's long-term strategy and decided to explore an expansion of its services and
client types in all sectors of the broad healthcare industry. The FCG Board
believed that the broad healthcare industry would continue to consolidate and
that various market sectors, such as the healthcare delivery, payor, government,
pharmaceutical and biotechnology sectors, would become closely related over
time. The FCG Board also believed that by hiring additional professionals and
acquiring complementary consulting firms it could expand its existing core
competencies in operations improvement and information management services.
During 1997, FCG assigned a team of senior level management personnel to conduct
a preliminary investigation of the viability of expanding FCG's services in the
pharmaceutical industry.
 
    After completing its initial public offering in the first quarter of 1998,
FCG confirmed its strategic commitment to acquiring complementary consulting
firms to expand its services and client types in a series of meetings of the FCG
Board and FCG's Operating Committee and Vice President's Council. In particular,
FCG determined that it would be strategically important to expand its
application development and integration services and to establish a long-term
presence in the pharmaceutical industry. As a result of this commitment, FCG
contacted Hambrecht & Quist to identify potential acquisitions of consulting
firms in certain industry segments, including the pharmaceutical industry.
 
   
    In May 1998, James A. Reep, Chairman and then CEO of FCG, was made aware of
ISCG. ISCG was brought to the attention of FCG by several parties, including
Hambrecht & Quist LLC ("Hambrecht & Quist").
    
 
    In the spring of 1997, management of ISCG began to evaluate alternatives to
ISCG remaining as an independent company. Additionally, certain key shareholders
of ISCG suggested that ISCG evaluate strategic alternatives. In the summer of
1997, ISCG initiated a process to identify potential strategic partners.
Throughout the remainder of 1997 and early 1998, ISCG made contact with a number
of such potential partners both directly and through its financial advisors.
 
   
    On April 7, 1998, at a meeting of the Executive Committee of the Board of
Directors of ISCG (the "ISCG Executive Committee") Robert W. Baird & Co.
Incorporated ("Baird") reviewed with the ISCG Executive Committee four written
indications of interest from potential partners, which did not include FCG.
After due analysis of each indication of interest, ISCG entered into a letter of
intent and " no shop" agreement with one such party on April 13, 1998 (the
"Prior Offer"). Shortly thereafter, ISCG and such third party initiated the
process of due diligence and negotiation of a definitive merger agreement.
During May of 1998, ISCG questioned whether the perceived cultural and economic
benefits from pursuing a potential transaction with this party would be
realized. In a series of communications with senior level management personnel
between the parties, Mr. Lipson expressed concern about these issues and certain
unresolved issues in the definitive merger agreement. The no-shop agreement with
such third party expired in late May.
    
 
    At the end of May 1998, Mr. Reep placed telephone calls to certain members
of ISCG's management. Mr. Lipson, Chairman and CEO of ISCG, subsequently called
Mr. Reep and the two met in person in early June of 1998 to discuss the
convergence of the provider, health plan and pharmaceutical sectors and the
potential strategic, cultural and operational synergies between the two
companies. Messrs. Reep and Lipson and several other members of the senior level
management personnel at ISCG subsequently met in early June of 1998. The agenda
of this meeting included additional discussions of strategic issues facing each
firm. At the conclusion of such meeting, Messrs. Reep and Lipson concluded that
additional discussions and due diligence were warranted and that a combination
of FCG and ISCG might potentially be in the best interests of the stockholders
and employees of both companies. A mutual non-disclosure agreement was executed
on June 8, 1998.
 
                                       39
<PAGE>
   
    On June 11 and June 12, 1998, Luther J. Nussbaum, then Executive Vice
President of FCG, and Mr. Lipson met at the principal executive offices of ISCG.
Representatives of Hambrecht & Quist and Baird, the financial advisors to each
of FCG and ISCG, respectively, were also present at this meeting. Messrs.
Nussbaum and Lipson discussed the historical and prospective financial and
operational performance of each company and outlined the key terms of a
potential transaction. Messrs. Nussbaum and Lipson agreed that any transaction
would be subject to the successful completion of comprehensive due diligence and
execution of a definitive merger agreement.
    
 
    On June 15, 1998, the FCG Board met for a regularly scheduled meeting.
During this meeting, certain management personnel, including Messrs. Reep and
Nussbaum, led a discussion regarding a potential acquisition of ISCG. During
this meeting the FCG Board approved the execution of a letter of intent for a
proposed merger of ISCG and FCG, and authorized and directed senior level
management personnel to continue discussions and negotiations with ISCG. The FCG
Board also directed such senior level management personnel to begin the due
diligence process as soon as practicable.
 
    On June 15, 1998, the ISCG Executive Committee met to discuss a potential
transaction with FCG. On June 18, 1998, the ISCG Executive Committee approved
the execution of a letter of intent, including a 30-day "no shop" agreement, for
a proposed merger of ISCG and FCG. This letter of intent was executed on June
18, 1998.
 
    On June 22, 1998, the ISCG Board of Directors held a special telephonic
meeting at which ISCG management updated the Board on the status of the
potential transaction with FCG.
 
   
    Beginning on June 22 and continuing through June 26, 1998, representatives
of FCG, ISCG, Hambrecht & Quist, Baird, Grant Thornton LLP ("Grant Thornton"),
KPMG Peat Marwick LLP ("KPMG"), Cooley Godward LLP ("Cooley Godward") counsel to
FCG, and Saul Ewing Remick & Saul, LLP ("Saul Ewing"), counsel to ISCG, met at
the ISCG Principal Offices to conduct due diligence with respect to financial,
operational and legal matters of ISCG. During these meetings, numerous
interviews and discussions took place among senior level management personnel of
both firms.
    
 
    On June 23, 1998, a draft of the definitive Reorganization Agreement was
delivered by Cooley Godward to Saul Ewing. Drafts of exhibits to the
Reorganization Agreement, including drafts of FCG and ISCG affiliate agreements,
FCG and ISCG voting agreements and the registration rights agreement, were
delivered to Saul Ewing on June 23 and June 24, 1998. A series of telephonic
conversations were held beginning on June 26, 1998 between representatives of
Saul Ewing and Cooley Godward to negotiate a definitive Reorganization Agreement
and related exhibits.
 
    Beginning on June 29 and continuing through July 1, 1998, representatives of
FCG, ISCG, Hambrecht & Quist, Baird, Grant Thornton, KPMG, Cooley Godward, and
Saul Ewing met at the offices of Cooley Godward in Palo Alto, California to
conduct due diligence with respect to financial, operational and legal matters
of FCG. During this period, representatives of FCG, ISCG, Saul Ewing and Cooley
Godward met to continue negotiation of a definitive Reorganization Agreement and
related exhibits. At the conclusion of these meetings, certain issues relating
to the representation and warranty and termination provisions in the
Reorganization Agreement, including issues relating to the Prior Offer, and the
registration rights agreement remained unresolved.
 
    On July 2, 1998, at a special meeting of the FCG Board, certain senior level
management personnel and representatives of Hambrecht & Quist and Cooley Godward
reviewed the terms of the proposed Merger and reported on the results of the due
diligence review of ISCG. In particular, Hambrecht & Quist made a presentation
regarding the financial terms of the proposed Merger. In addition, the terms of
the Reorganization Agreement and related exhibits were discussed in detail with
the FCG Board. After these discussions, Hambrecht & Quist rendered its oral
opinion that, as of such date, the Exchange Ratio was fair from a financial
point of view to FCG. The meeting was concluded with the expectation that the
FCG Board would meet again on July 6, 1998 to consider and vote on the proposed
Merger with ISCG. At the
 
                                       40

conclusion of these meetings, certain issues relating to the representation and
warranty and termination provisions in the Reorganization Agreement, including
issues relating to the Prior Offer, remained unresolved.
 
    On July 2, 1998, at a meeting of the ISCG Board of Directors, certain senior
level management personnel and representatives of Baird and Saul Ewing reviewed
the terms of the proposed Merger and reported on the results of the due
diligence review of FCG. The ISCG Board of Directors evaluated the merits of the
transaction, including the proposed Exchange Ratio and the cultural
compatibility between FCG and ISCG.
 
    On July 6, 1998, at a special meeting of the FCG Board, the FCG Board voted
unanimously: (1) subject to, among other things, the satisfactory completion of
the pre-acquisition review of ISCG by FCG's legal and financial advisors, the
delivery of Hambrecht & Quist's fairness opinion, and the resolution of the
aforementioned outstanding issues, to approve the proposed merger with ISCG, the
Reorganization Agreement and related exhibits as presented to them, and to
authorize and direct the officers of FCG to finalize the terms of the
Reorganization Agreement, and (2) to recommend that the FCG stockholders vote to
approve the issuance of FCG Common Stock in the merger. In particular, the FCG
Board noted that satisfactory resolution of the representation and warranty and
termination provisions in the Reorganization Agreement was critical to the
completion of the Merger.
 
    On July 6, 1998, the ISCG Board of Directors met to consider the approval of
the proposed transaction with FCG. The ISCG Board of Directors considered, among
other things, the potential benefits of the proposed Merger, the risks of the
Merger and the results of the due diligence process. In addition, Baird made a
presentation regarding the financial terms of the proposed Merger and provided
the ISCG Board with a financial analysis with respect to such terms. In
addition, the terms of the Reorganization Agreement and related exhibits were
discussed in detail with the ISCG Board of Directors. The ISCG Board of
Directors approved the transaction subject to a resolution, satisfactory to the
Executive Committee of the Board of Directors, of the representation and
warranty and termination provisions in the Reorganization Agreement and the
delivery of Baird's fairness opinion.
 
    From July 6 to July 8, 1998, the representatives of FCG and ISCG attempted
to resolve issues in the representation and warranty and termination provisions
in the Reorganization Agreement, including issues relating to the Prior Offer.
Failing to resolve these issues, on July 8, 1998, Mr. Reep, in a telephone call
with Mr. Lipson and in a subsequent written confirmation, terminated
negotiations between FCG and ISCG. On August 26, 1998, ISCG executed an
agreement (the "Release Agreement") that it believes resolved open issues
relating to the Prior Offer. The Release Agreement included a complete release
of claims between ISCG and such third party. ISCG expects to recognize expenses
in the amount of approximately $275,000 after tax in the third quarter of 1998
for due diligence, accounting, legal and other costs arising in connection with
the Prior Offer, including a payment made in connection with the Release
Agreement.
 
    After the execution of the Release Agreement, in a series of telephone
conferences between senior level management personnel, FCG and ISCG decided to
resume negotiations. Beginning on September 1 and continuing through September
3, 1998, representatives of FCG, ISCG, Hambrecht & Quist, Baird, Grant Thornton
and KPMG met at the offices of Saul Ewing in Berwyn, Pennsylvania to update the
financial and operational due diligence from the previous review in June of
1998. Simultaneously, legal due diligence materials were exchanged among the
legal advisors to FCG and ISCG. Negotiations were held telephonically among the
legal advisors of FCG and ISCG from September 1 until September 9, 1998 to reach
final agreement on the terms of the definitive Reorganization Agreement.
 
    The ISCG Board of Directors met on the morning of September 9, 1998, to
consider the definitive Reorganization Agreement. After due consideration,
including a detailed review of the Reorganization Agreement and Merger
evaluation of the oral opinion of Baird, subsequently confirmed in writing, that
the Exchange Ratio was fair, from a financial point of view, to the holders of
ISCG Common Stock (other than
 
                                       41
<PAGE>
FCG and its affiliates), the ISCG Board of Directors unanimously approved the
Reorganization Agreement and the related exhibits. The ISCG Board of Directors
also voted unanimously in favor of recommending the approval of the
Reorganization Agreement and Merger to the ISCG Shareholders.
 
    On September 9, 1998, in a special meeting of the FCG Board, certain senior
level management personnel and representatives of Hambrecht & Quist and Cooley
Godward reviewed the finalized terms of the proposed Merger and reported on the
results of the due diligence review of ISCG. In particular, Hambrecht & Quist
made a presentation regarding the analysis described under "Approval of the
Merger and Related Transactions--Opinion of Financial Advisor to FCG." In
addition, the terms of the Reorganization Agreement and related exhibits were
discussed in detail with the FCG Board. After these discussions, Hambrecht &
Quist rendered its oral opinion, subsequently confirmed in writing, that, as of
such date, the Exchange Ratio was fair from a financial point of view to FCG.
After such presentations and discussions, the FCG Board voted unanimously: (1)
to approve the proposed Merger with ISCG, the Reorganization Agreement and
related exhibits as presented to them; and (2) to recommend that the FCG
stockholders vote to approve the issuance of FCG Common Stock in the Merger.
 
    Following the approval of the FCG Board of Directors and the ISCG Board of
Directors, the Reorganization Agreement in its definitive form was executed and
jointly announced in the evening of September 9, 1998.
 
JOINT REASONS FOR THE MERGER
 
   
    The Boards of Directors of FCG and ISCG believe that the proposed Merger
will afford to each company the complementary strengths of the two individual
companies, will provide the Combined Company with several potential benefits and
may enable the combined company (the "Combined Company") to address emerging
strategic opportunities in the healthcare industry quickly and effectively.
    
 
    The potential benefits to the Combined Company include the following:
 
    - The combination of FCG's broad industry expertise, information technology
      strategic planning skills and program management methods and ISCG's deep
      information technology skills allows the Combined Company to offer a
      broader range and scope of services to the pharmaceutical and
      biotechnology industries.
 
    - The combination of FCG's and ISCG's application development and
      integration practices allows the Combined Company to compete more
      effectively in the provision of these services to clients in the
      healthcare industry.
 
    - The combination of FCG's and ISCG's experience, financial resources,
      consultants and service offerings allows the Combined Company to share
      knowledge and client opportunities and, as a result, enable the Combined
      Company to respond quickly and effectively to emerging opportunities in
      the healthcare industry.
 
    - The Combined Company may offer a greater range of career opportunities for
      employees and may improve retention over time.
 
    - The Combined Company would potentially be able to operate with a reduced
      level of general and administrative expenses.
 
    FCG and ISCG have each identified additional reasons for the Merger, as
discussed below. It should be noted, however, that the potential benefits of the
Merger may not be realized. See "Risk Factors."
 
ISCG'S REASONS FOR THE MERGER
 
    During the spring of 1997, senior level management personnel of ISCG, at the
direction of the ISCG Board of Directors, decided that ISCG would seek a
strategic partner. Reasons for this decision included
 
                                       42
<PAGE>
the need for ISCG to become a larger entity in a consolidating marketplace,
obtain additional technological and geographic presence to compete with national
and international competitors, and continue to provide additional challenging
positions necessary to recruit and retain skilled employees in a highly
competitive marketplace.
 
    In addition to the anticipated joint benefits described above, the ISCG
Board of Directors believes that the following are additional reasons that the
Merger will be beneficial to ISCG:
 
    - ISCG believes that the greater size of the Combined Company will enable it
      to secure larger and more complex projects from its clients.
 
    - The strategic consulting experience of FCG may offer ISCG the ability to
      market its consulting services to more senior level decision-makers at its
      customers.
 
    - The merger may provide enhanced career opportunities for ISCG's employees.
 
    In addition to the factors set forth above, in the course of its meetings
during June, July, August and September of 1998, the ISCG Board of Directors
reviewed and considered a wide variety of information relevant to the Merger
including: (i) information concerning FCG's and ISCG's respective businesses,
historical financial performance and conditions, operations, services, clients,
competitive positions, prospects and management; (ii) ISCG's management's view
as to the financial conditions results of operations and business and financial
potential of FCG and ISCG before and after giving effect to the Merger, based on
management's due diligence; (iii) current financial market conditions and
historical trading market prices, volatility and trading information with
respect to FCG Common Stock and ISCG Common Stock; (iv) the consideration to be
paid to the ISCG shareholders in the Merger and the relationship between the
market value of comparable merger transactions; (v) the belief that the terms of
the Reorganization Agreement, including the parties' representations, warranties
and covenants, and the conditions to their respective obligations, are
reasonable; (vi) reports from management, legal and financial advisors as to the
results of their due diligence investigation of FCG; (vii) the potential impact
of the Merger on clients and employees of FCG and ISCG; (viii) the likely
reaction to the Merger from the financial markets; and (ix) the financial
analysis and pro forma and other information with respect to the companies
presented by management and Baird in presentations to the ISCG Board of
Directors, as well as Baird's opinion to the effect that the Exchange Ratio was
fair, from a financial point of view, to the holders of ISCG Common Stock (other
than FCG and its affiliates). A copy of Baird's opinion is attached hereto as
Appendix B-1 and ISCG shareholders are urged to review it carefully and in its
entirety.
 
    The ISCG Board of Directors also considered a number of potentially negative
factors in its deliberations concerning the Merger, including (i) the potential
disruption to the business of both companies following announcement of the
Merger, including the effects of employee uncertainty, the possibility that key
employees may leave FCG or ISCG, and the possibility that key clients may not
approve of the Merger or may determine to terminate their relationship with the
Combined Company; (ii) the dilutive effects of the issuance of shares in the
Merger and the higher level of expenses that will be borne by the Combined
Company; (iii) additional potential problems and costs associated with the
integration of both companies into a single enterprise; (iv) the possibility
that the Merger would not be consummated; and (v) the other risks described
under "Risk Factors" herein. After due consideration, the ISCG Board of
Directors concluded that the benefits of the transaction to ISCG and its
shareholders outweighed the risks associated with the foregoing factors.
 
    The foregoing discussion of the factors considered by the ISCG Board of
Directors is not intended to be exhaustive but is intended to include
substantially all of the material facts considered by the ISCG Board of
Directors. In view of the complexity and variety of factors considered by the
ISCG Board of Directors, the ISCG Board of Directors did not consider it
practical to quantify or otherwise attempt to assign and relative or specific
weights to the specific factors considered, and individual directors may have
given differing weights to different factors.

FCG'S REASONS FOR THE MERGER
 
    At meetings convened on June 15, July 2, July 6 and September 9, 1998, the
FCG Board of Directors determined that the Reorganization Agreement and the
transactions contemplated thereby were in the best interests of FCG and its
stockholders, approved and adopted the Reorganization Agreement and the
transactions contemplated thereby, and unanimously recommended that the FCG
stockholders approve the issuance of FCG Common Stock in connection with the
Merger. In reaching the foregoing conclusions and recommendations, the FCG Board
of Directors considered a number of factors, including the following:
 
    - The convergence of several sectors within the healthcare industry.
 
    - The combination would enhance FCG's service offerings and increase FCG's
      client base in the increasingly interrelated healthcare industry. FCG
      believes that the healthcare industry may see increasing interaction among
      genetic engineering, drug development, disease management, care management
      in general and care delivery.
 
    - The combination of FCG and ISCG would strengthen FCG's application
      development capability in client-server architecture, web-based
      applications, object-oriented and relational databases, and cross-platform
      systems integration.
 
    In addition to the factors set forth above, in the course of its meetings
during June, July, July and September of 1998 the FCG Board of Directors
reviewed and considered a wide variety of information relevant to the Merger
including: (i) information concerning FCG's and ISCG's respective businesses,
historical financial performance and conditions, operations, services, clients,
competitive positions, prospects and management; (ii) FCG's management's view as
to the financial condition, results of operations and business and financial
potential of FCG and ISCG before and after giving effect to the Merger, based on
management's due diligence; (iii) current financial market conditions and
historical trading market prices, volatility and trading information with
respect to FCG Common Stock and ISCG Common Stock; (iv) the consideration to be
paid to the ISCG shareholders in the Merger and the relationship between the
market value of comparable merger transactions; (v) the belief that the terms of
the Merger Agreement, including the parties' representations, warranties and
covenants, and the conditions to their respective obligations, are reasonable;
(vi) reports from management, legal and financial advisors as to the results of
their due diligence investigation of ISCG; (vii) the potential impact of the
Merger on clients and employees of FCG and ISCG; (viii) the likely reaction to
the Merger from the financial markets; and (ix) the financial analysis and pro
forma and other information with respect to the companies presented by
management and Hambrecht & Quist in presentations to the FCG Board of Directors,
as well as Hambrecht & Quist's opinion that, as of September 9, 1998, the
Exchange Ratio was fair from a financial point of view to FCG (a copy of which
opinion is attached hereto as Appendix B-2 and which opinion stockholders are
urged to review carefully and in its entirety).
 
    The FCG Board of Directors also considered a number of potentially negative
factors in its deliberations concerning the Merger, including (i) the potential
disruption to the business of both companies following announcement of the
Merger, including the effects of employee uncertainty, the possibility that key
employees may leave FCG of ISCG, and the possibility that key clients may not
approve of the Merger or may determine to terminate their relationship with the
Combined Company; (ii) the dilutive effects of the issuance of shares in the
Merger and the higher level of expenses that will be borne by the Combined
Company; (iii) additional potential problems and costs associated with the
integration of both companies into a single enterprise; (iv) the possibility
that the Merger would not be consummated; and (v) the other risks described
under "Risk Factors" herein. After due consideration, the FCG Board of Directors
concluded that the benefits of the transaction to FCG and its stockholders
outweighed the risks associated with the foregoing factors.

OPINION OF FINANCIAL ADVISOR TO ISCG
 
    ISCG retained Baird to act as its financial advisor in connection with the
possible sale of ISCG. As part of such services, ISCG requested that Baird
render its opinion as to the fairness, from a financial point of view, of the
Exchange Ratio to the holders of ISCG Common Stock (other than FCG and its
affiliates). On September 9, 1998, Baird rendered its opinion to the ISCG Board
of Directors to the effect that, as of such date, the Exchange Ratio was fair,
from a financial point of view, to the holders of ISCG Common Stock (other than
FCG and its affiliates).
 
   
    THE FULL TEXT OF THE OPINION DELIVERED BY BAIRD TO THE ISCG BOARD OF
DIRECTORS DATED SEPTEMBER 9, 1998 (THE "BAIRD OPINION"), WHICH SETS FORTH THE
ASSUMPTIONS MADE, GENERAL PROCEDURES FOLLOWED, MATTERS CONSIDERED AND
LIMITATIONS ON THE SCOPE OF REVIEW UNDERTAKEN BY BAIRD IN RENDERING ITS OPINION,
IS ATTACHED AS APPENDIX B-1 TO THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS
INCORPORATED HEREIN BY REFERENCE. THE BAIRD OPINION IS DIRECTED ONLY TO THE
FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE EXCHANGE RATIO TO THE HOLDERS
OF ISCG COMMON STOCK (OTHER THAN FCG AND ITS AFFILIATES) AND DOES NOT CONSTITUTE
A RECOMMENDATION TO ANY ISCG SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE
WITH RESPECT TO THE REORGANIZATION AGREEMENT. THE SUMMARY OF BAIRD'S OPINION SET
FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH
OPINION ATTACHED HERETO AS APPENDIX B-1. ISCG SHAREHOLDERS ARE URGED TO READ THE
OPINION CAREFULLY AND IN ITS ENTIRETY.
    
 
   
    In conducting its investigation and analysis and in arriving at its opinion,
Baird reviewed such information and took into account such financial and
economic factors as it deemed relevant under the circumstances. In that
connection, Baird, among other things: (i) reviewed certain internal
information, primarily financial in nature, including projections, concerning
the business and operations of ISCG and FCG furnished to Baird for purposes of
its analysis, as well as publicly available information including but not
limited to ISCG's and FCG's recent filings with the Securities and Exchange
Commission (the "SEC") and equity analyst research reports prepared by various
investment banking firms, including Baird; (ii) reviewed the Reorganization
Agreement in the form presented to ISCG's Board of Directors; (iii) compared the
historical market prices and trading activity of ISCG Common Stock and FCG
Common Stock with those of certain other publicly traded companies Baird deemed
relevant; (iv) compared the financial position and operating results of ISCG and
FCG with those of other publicly traded companies Baird deemed relevant; and (v)
compared the proposed financial terms of the Merger with the financial terms of
certain other business combinations Baird deemed relevant. Baird held
discussions with members of ISCG's and FCG's respective senior managements
concerning ISCG's and FCG's historical and current financial condition and
operating results, as well as the future prospects of ISCG and FCG,
respectively. As a part of its engagement, Baird was requested to, and did,
solicit third party indications of interest in acquiring ISCG. Baird also
considered such other information, financial studies, analyses and
investigations and financial, economic and market criteria which Baird deemed
relevant for the preparation of its opinion. ISCG and FCG determined the
Exchange Ratio in arms-length negotiations. ISCG did not place any limitation
upon Baird with respect to the procedures followed or factors considered by
Baird in rendering its opinion.
    
 
    In arriving at its opinion, Baird assumed and relied upon the accuracy and
completeness of all of the financial and other information that was publicly
available or provided to Baird by or on behalf of ISCG and FCG, and was not
engaged to independently verify any such information. Baird assumed, with ISCG's
consent, that: (i) all material assets and liabilities (contingent or otherwise,
known or unknown) of ISCG
 
                                       45
<PAGE>
and FCG are as set forth in their respective financial statements; (ii) the
Merger will be accounted for under the pooling-of-interests method; and (iii)
the Merger will be consummated in accordance with the terms set forth in the
Reorganization Agreement, without any amendment thereto and without waiver by
ISCG or FCG of any of the conditions to their respective obligations thereunder.
At ISCG's direction, Baird assumed that no cost savings or operating synergies
will result from the Merger, and excluded transaction costs from its financial
analysis. Baird also assumed that the financial forecasts examined by it were
reasonably prepared on bases reflecting the best available estimates and good
faith judgments of ISCG's and FCG's respective senior managements as to future
performance of ISCG and FCG, respectively. In conducting its review, Baird did
not undertake nor obtain an independent evaluation or appraisal of any of the
assets or liabilities (contingent or otherwise) of ISCG or FCG nor did it make a
physical inspection of the properties or facilities of ISCG or FCG. Baird's
opinion necessarily was based upon economic, monetary and market conditions as
they existed and could be evaluated on the date of its opinion, and did not
predict or take into account any changes which may occur, or information which
may become available, after the date of such opinion. Furthermore, Baird
expressed no opinion as to the price or trading range at which any of ISCG's or
FCG's securities (including ISCG Common Stock and FCG Common Stock) will trade
following the date of such opinion.
 
    The following is a summary of the material financial analyses performed by
Baird in connection with rendering its opinion.
 
    ANALYSIS OF ISCG'S VALUATION PREMIUMS.  Baird calculated the "Implied Equity
Value Per Share" reflected by the terms of the Merger to be $13.19 for each
share of ISCG Common Stock, obtained by multiplying the Exchange Ratio of 0.77
by the closing price per share of FCG Common Stock of $17.13 on September 4,
1998. Baird compared the premium to holders of ISCG Common Stock represented by
the Implied Equity Value Per Share of $13.19 to the closing prices for ISCG
Common Stock on such date and on the dates seven days, 30 days, 60 days, 90
days, 180 days and 52 weeks prior to the September 9, 1998 ISCG Board of
Directors meeting. Baird calculated that the Implied Equity Value Per Share
represented the following premiums or discounts to holders of ISCG Common Stock:
(i) a premium of 35.2% over the closing price of $9.75 for ISCG Common Stock on
September 4, 1998; (ii) a premium of 25.6% over the closing price of $10.50 for
ISCG Common Stock seven days prior to the date of its opinion; (iii) a premium
of 7.6% over the closing price of $12.25 for ISCG Common Stock 30 days prior to
the date of its opinion; (iv) a discount of 2.3% over the closing price of
$13.50 for ISCG Common Stock 60 days prior to the date of its opinion; (v) a
discount of 0.5% over the closing price of $13.25 for ISCG Common Stock 90 days
prior to the date of its opinion; (vi) a premium of 7.6% over the closing price
of $12.25 for ISCG Common Stock 180 days prior to the date of its opinion; and
(vii) a premium of 0.5% over the closing price of $13.13 for ISCG Common Stock
52 weeks prior to the date of its opinion. Baird noted that the premiums and
discounts of the Implied Equity Value relative to ISCG Common Stock price over
certain historical time periods were influenced by the significant volatility
and price declines experienced recently in the equity capital markets in general
and for information technology service companies in particular. Baird also
performed an analysis of the implied historical transaction premium, based upon
the Exchange Ratio of 0.77 and the closing market price per share of ISCG Common
Stock and FCG Common Stock, for each trading day from July 2, 1998 to September
4, 1998. This analysis yielded an average premium of 51.4%, and a high and low
premium of 90.4% and 21.4%, respectively, relative to the premium of 35.2% based
on the closing market price per share of ISCG Common Stock and FCG Common Stock
on September 4, 1998.
 
    ANALYSIS OF ISCG VALUATION MULTIPLES.  Baird calculated the "Implied Total
Equity Value" and "Implied Enterprise Value" of ISCG as a result of the Merger
to be $119.15 million and $115.13 million, respectively. The Implied Total
Equity Value was obtained by multiplying the Implied Equity Value Per Share by
the total number of outstanding shares of ISCG Common Stock, including shares
issuable upon exercise of stock options and warrants outstanding as of August
31, 1998, less net proceeds from the exercise of such stock options and
warrants. The Implied Enterprise Value was obtained by adding ISCG's
 
                                       46
<PAGE>
outstanding total debt and subtracting ISCG's cash and cash equivalents balances
(as of July 31, 1998 as provided to Baird by ISCG management) to the Implied
Total Equity Value. In performing its analysis, Baird used, among other items,
operating statistics for ISCG's latest twelve months ended June 30, 1998
("LTM"), as provided by ISCG management. Baird calculated multiples of the
Implied Total Equity Value to ISCG's LTM net income and its projected net income
for calendar years 1998 and 1999 (based on ISCG management's estimates) and
multiples of ISCG's Implied Enterprise Value to its LTM sales, operating income
before depreciation and amortization, interest and taxes ("EBITDA") and its
operating income ("EBIT"). The calculations resulted in multiples of the Implied
Total Equity Value to net income ("P/E Ratios") of 27.6x based on LTM results,
23.8x based on projected 1998 results and 17.2x based on projected 1999 results.
The ratio of Implied Enterprise Value to LTM sales was 2.1x, the ratio of
Implied Enterprise Value to LTM EBITDA was 13.5x and the ratio of Implied
Enterprise Value to LTM EBIT was 16.6x.
 
    IMPLIED EXCHANGE RATIO ANALYSIS.  Baird performed an analysis of the
historical trading ratio between ISCG Common Stock and FCG Common Stock based on
the closing market price per share of ISCG Common Stock relative to the closing
market price per share of FCG Common Stock for each trading day from July 2,
1998 to September 4, 1998. This analysis yielded an average historical trading
ratio of 0.52, and a high and low single day exchange ratio of 0.63 and 0.40,
respectively, significantly below the Exchange Ratio of 0.77.
 
    ANALYSIS OF SELECTED PUBLICLY TRADED ISCG COMPARABLE COMPANIES.  Baird
reviewed certain publicly available financial information as of the most
recently reported period and stock market information as of September 3, 1998,
for 15 publicly traded companies that Baird deemed relevant. Such comparable
companies consisted of information technology professional services companies.
For each comparable company, Baird calculated multiples, as of September 3,
1998, of Enterprise Value to LTM sales, LTM EBITDA and LTM EBIT. Baird then
compared these multiples to the relevant ISCG multiples based on the Implied
Equity Price Per Share. An analysis of the multiples of Enterprise Value to LTM
sales, LTM EBITDA and LTM EBIT yielded 2.1x, 13.5x and 16.6x, respectively, for
ISCG compared to medians of 1.7x, 12.5x and 15.1x, respectively, for ISCG's
comparable companies. For ISCG and each comparable company, Baird also
calculated P/E Ratios based upon the Implied Equity Value Per Share for ISCG and
the closing stock prices as of September 3, 1998 for the comparable companies
and net income statistics for LTM and projected 1998 and 1999. An analysis of
the P/E Ratios based on ISCG's net income for LTM and projected 1998 and 1999
yielded 27.6x, 23.8x and 17.2x, respectively, compared to LTM, projected 1998
and 1999 medians of 23.6x, 21.3x and 17.7x, respectively, for ISCG's comparable
companies.
 
    ANALYSIS OF SELECTED PUBLICLY TRADED FCG COMPARABLE COMPANIES.  In order to
assess the relative public market valuation of FCG Common Stock to be used by
FCG in exchange for ISCG Common Stock, Baird reviewed certain publicly available
financial information as of the most recently reported period and stock market
information as of September 3, 1998, for ten publicly traded companies which
Baird deemed relevant. Such comparable companies consisted of health care
information technology services and related companies. For each comparable
company, Baird calculated multiples as of September 3, 1998, of Enterprise Value
to LTM sales, LTM EBITDA and LTM EBIT. Baird then compared these multiples to
the relevant FCG multiples based on FCG's closing share price of $17.125 on
September 4, 1998, and FCG's LTM operating performance statistics, as provided
to Baird by FCG's management. An analysis of the multiples of Enterprise Value
to sales, EBITDA and EBIT yielded 2.1x, 17.6x and 21.6x, respectively, for FCG
compared to median ratios of 2.7x, 15.1x and 24.4x, respectively, for FCG's
comparable companies. For FCG and each comparable company, Baird also calculated
P/E Ratios based on the closing stock prices as of September 4, 1998, for FCG
and September 3, 1998, for the comparable companies and LTM earnings per share
and estimated earnings per share for 1998 and 1999. An analysis of the P/E
Ratios based on earnings per share for FCG's LTM and projected 1998 and 1999
(based on First Call consensus estimates) yielded 35.7x, 34.3x and 27.2x,
respectively, compared to LTM and projected 1998 and 1999 medians of 26.1x,
28.4x and 21.2x, respectively, for FCG's comparable companies.

    ANALYSIS OF SELECTED COMPARABLE ACQUISITION TRANSACTIONS.  Baird reviewed
selected acquisition transactions which Baird deemed relevant. Such transactions
were chosen based on a review of acquired companies that possessed general
business, operating and financial characteristics representative of companies in
the industry in which ISCG operates. Baird noted that none of the selected
transactions reviewed was identical to the Merger and that, accordingly, the
analysis of comparable transactions necessarily involves complex consideration
and judgments concerning differences in financial and operating characteristics
of ISCG and other factors that would affect the acquisition value of comparable
transactions including, among others, the general market conditions prevailing
in the equity capital markets at the time of such transaction. For each
comparable transaction, Baird calculated multiples of Enterprise Value to LTM
sales, LTM EBITDA and LTM EBIT, calculated P/E Ratios based on LTM net income
and estimated net income one and two years forward (from the time of the
announcement of each specific acquisition transaction), and calculated the
premiums paid for the equity in these transactions over the public market value
of the equity at various times prior to the announcement of such transaction.
Baird then compared those multiples and premiums to the relevant ISCG multiples
and premiums. These calculations yielded multiples of Enterprise Value to LTM
sales, LTM EBITDA and LTM EBIT of 2.1x, 13.5x and 16.6x, respectively, for ISCG,
compared to the LTM medians of 1.7x, 20.9x and 24.7x, respectively, for the
comparable acquisition transactions. An analysis of the P/E Ratios based on LTM
earnings per share and estimated earnings one and two years forward (from the
time of the announcement of each specific acquisition transaction) yielded
27.6x, 23.8x and 17.2x for ISCG, respectively, compared to a LTM and one and two
year estimated earnings medians of 40.8x, 32.6x and 24.9x for the comparable
transactions, respectively. An analysis of the Implied Equity Value Per Share to
the closing price of ISCG Common Stock one day, 30 days and 90 days prior to the
announcement date, compared to the prices paid for the equity in such comparable
acquisition transactions relative to the market value of equity one day, 30 days
and 90 days prior to the announcement date of such transactions, yielded a one
day premium of 35.2%, a 30 day premium of 7.6% and a 90 day discount of 0.5% for
ISCG, compared to median premiums of 32.2%, 52.0% and 33.3%, respectively, for
the comparable acquisition transactions. As mentioned earlier, the average one
day premium based on the Exchange Ratio of 0.77 and the daily closing prices per
share of ISCG Common Stock and FCG Common Stock for the two month period prior
to the announcement date was 51.2% with a high and low one day premium of 90.4%
and 21.4%, respectively. Baird noted that ISCG's Implied Enterprise Value and
P/E multiples and ISCG Common Stock price over certain historic time periods
were influenced by the significant volatility and price declines experienced
recently in the equity capital markets in general and for information technology
service companies in particular.
 
    CONTRIBUTION ANALYSIS.  Baird analyzed ISCG's and FCG's relative
contribution to the Combined Company with respect to certain measurements,
including net sales, gross profit, EBIT and net income. As a result of the
Merger, ISCG's shareholders will own approximately 28.9% of the outstanding FCG
Common Stock assuming an Exchange Ratio of 0.77. This compares to ISCG's
contribution, based on projected 1998 and 1999 statistics for the Combined
Company, of approximately 33.1% to 33.5% of net sales, 30.6% to 31.8% of gross
profit, 38.1% to 40.0% of EBIT and 36.6% to 38.8% of net income.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Baird performed a discounted cash flow
analysis of ISCG on a stand alone basis using management's projections for 1998
through 2002 without taking into account any potential cost savings and
synergies which may be realized following the Merger. In such analysis, Baird
assumed terminal value multiples of 12.0x to 16.0x EBIT in the year 2002 and
discount rates of 21.0% to 25.0%. Such analysis produced implied values of ISCG
Common Stock ranging from $12.68 to $19.13 per share.
 
    In order to assess the relative public market valuation of FCG Common Stock
to be used by FCG in exchange for ISCG Common Stock, Baird performed a
discounted cash flow analysis of FCG, on a stand alone basis, using FCG
management's projections for 1998 through 2002 without taking into account any
potential cost savings and synergies which may be realized following the Merger.
In such analysis, Baird
 
                                       48
<PAGE>
assumed terminal value multiples of 22.0x to 26.0x EBIT in the year 2002 and
discount rates of 21.0% to 25.0%. Such analysis produced implied values of FCG
Common Stock ranging from $20.45 to $27.19 per share.
 
   
    PRO FORMA MERGER ANALYSIS.  Baird prepared pro forma analyses of the
financial impact of the Merger. In conducting its analysis, Baird relied upon
certain assumptions described above and projected earnings estimates for ISCG
(prepared by ISCG management) and FCG (prepared by FCG management). Baird
compared the earnings per share of FCG Common Stock, on a stand-alone basis, to
the earnings per share of the common stock of the Combined Company on a pro
forma basis. The analysis (assuming no transaction-related expenses, cost
savings or synergies) indicated that the proposed transaction would be accretive
to FCG's stockholders on an earnings per share basis in 1998 and 1999. The
results of the pro forma merger analysis are not necessarily indicative of
future operating results or financial position.
    
 
    The foregoing summary does not purport to be a complete description of the
analyses performed by Baird. The preparation of a fairness opinion is a complex
process and is not susceptible to partial analysis or summary description. Baird
believes that its analyses must be considered as a whole, and that selecting
portions of such analyses without considering all analyses and factors, would
create an incomplete view of the processes underlying its opinion. Baird did not
attempt to assign specific weights to particular analyses. Any estimates
contained in Baird's analyses are not necessarily indicative of actual values,
which may be significantly more or less favorable than as set forth therein.
Estimates of values of companies do not purport to be appraisals or necessarily
to reflect the prices at which companies may actually be sold. Because such
estimates are inherently subject to uncertainty, Baird does not assume
responsibility for their accuracy.
 
    Baird, as part of its investment banking business, is engaged in the
evaluation of businesses and their securities in connection with mergers and
acquisitions, negotiated underwritings, competitive biddings, secondary
distributions of listed and unlisted securities, private placements, and
valuations for estate, corporate and other purposes. ISCG retained Baird because
of its experience and expertise in the valuation of businesses and their
securities in connection with mergers and acquisitions. In the ordinary course
of business, Baird may from time to time trade equity securities of ISCG and FCG
for its own account and for accounts of its customers and, accordingly, may at
any time hold a long or short position in such securities.
 
    COMPENSATION.  Pursuant to an engagement letter dated February 10, 1998 (as
amended) between ISCG and Baird, ISCG agreed to pay Baird, upon the transaction
date, a transaction fee equal to specified percentages of the total
consideration paid. Upon the transaction closing, Baird shall be paid a
transaction fee equal to 1.0% on the amount of total consideration up to $125.0
million, plus 2.0% on the total consideration amount between $125.0 million and
$175.0 million and 3.0% on the total consideration amount over $175.0 million.
For delivering its fairness opinion on September 9, 1998, Baird is entitled to
receive a fee of $400,000, payable upon delivery of its opinion, regardless of
the conclusions reached by Baird in such opinion, with such amount fully
credited against the transaction fee discussed above. ISCG has also agreed to
reimburse Baird for certain of its reasonable out-of-pocket expenses. ISCG has
also agreed to indemnify Baird, its affiliates and their respective directors,
officers, employees and agents and controlling persons against certain
liabilities relating to or arising out of its engagement, including liabilities
under the federal securities laws. In the past, Baird has performed investment
banking services for ISCG, including acting as co-manager in ISCG's 1996 public
offering of ISCG's Common Stock. Additionally, in the past, Baird has performed
investment banking services for Safeguard Scientifics, Inc., an affiliate of
ISCG, as well as for certain other affiliates of Safeguard Scientifics, Inc.,
for which Baird has received customary compensation.

OPINION OF FINANCIAL ADVISOR TO FCG
 
    FCG engaged Hambrecht & Quist to act as its exclusive financial advisor in
connection with the Merger and to render an opinion as to the fairness from a
financial point of view to FCG of the Exchange Ratio. Hambrecht & Quist was
selected by the FCG Board of Directors based on Hambrecht & Quist's
qualifications, expertise and reputation, as well as Hambrecht & Quist's
historic investment banking relationship and familiarity with FCG. Hambrecht &
Quist rendered its oral opinion (subsequently confirmed in writing) on September
9, 1998 to the Board of Directors that, as of such date, the Exchange Ratio is
fair to FCG from a financial point of view.
 
   
    THE FULL TEXT OF THE OPINION DELIVERED BY HAMBRECHT & QUIST TO THE FCG BOARD
OF DIRECTORS, DATED SEPTEMBER 9, 1998 (THE "HAMBRECHT & QUIST OPINION"), WHICH
SETS FORTH THE ASSUMPTIONS MADE, GENERAL PROCEDURES FOLLOWED, MATTERS CONSIDERED
AND LIMITATIONS ON THE SCOPE OF REVIEW UNDERTAKEN BY HAMBRECHT & QUIST IN
RENDERING ITS OPINION, IS ATTACHED AS APPENDIX B-2 TO THIS JOINT PROXY
STATEMENT/ PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. THE HAMBRECHT &
QUIST OPINION IS DIRECTED ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW,
OF THE EXCHANGE RATIO TO FCG AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY FCG
STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD VOTE WITH RESPECT TO THE
REORGANIZATION AGREEMENT. THE SUMMARY OF THE HAMBRECHT & QUIST OPINION SET FORTH
BELOW IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION
ATTACHED HERETO AS APPENDIX B-2. FCG STOCKHOLDERS ARE URGED TO READ THE OPINION
CAREFULLY AND IN ITS ENTIRETY.
    
 
   
    In its review of the Merger, and in arriving at its opinion, Hambrecht &
Quist, among other things: (i) reviewed the publicly available consolidated
financial statements FCG for recent years and interim periods to date and
certain other relevant financial and operating data of FCG made available to it
from published sources and from the internal records of FCG; (ii) reviewed
certain internal financial and operating information, including certain
projections, relating to FCG prepared by the management of FCG; (iii) discussed
the business, financial condition and prospects of FCG with certain of its
officers; (iv) reviewed the publicly available consolidated financial statements
of ISCG for recent years and interim periods to date and certain other relevant
financial and operating data of ISCG made available to it from published sources
and from the internal records of ISCG; (v) reviewed certain internal financial
and operating information, including certain projections, relating to ISCG
prepared by the management of ISCG; (vi) discussed the business, financial
condition and prospects of ISCG with certain of its officers; (vii) reviewed the
recent reported prices and trading activity for the common stocks of FCG and
ISCG and compared such information and certain financial information for FCG and
ISCG with similar information for certain other companies engaged in businesses
it considers comparable; (viii) reviewed the financial terms, to the extent
publicly available, of certain comparable merger and acquisition transactions;
(ix) reviewed the Reorganization Agreement; and (x) performed such other
analyses and examinations and considered such other information, financial
studies, analyses and investigations and financial, economic and market data as
Hambrecht & Quist deemed relevant.
    
 
    Hambrecht & Quist did not independently verify any of the information
concerning FCG or ISCG considered in connection with its review of the Merger
and, for purposes of its opinion, Hambrecht & Quist assumed and relied upon the
accuracy and completeness of all such information. In connection with its
opinion, Hambrecht & Quist did not prepare or obtain any independent valuation
or appraisal of any of the assets or liabilities of FCG or ISCG, nor did it
conduct a physical inspection of the properties and facilities of FCG or ISCG.
With respect to the financial forecasts and projections used in its analysis,
Hambrecht & Quist assumed that they reflected the best currently available
estimates and judgments of the expected future financial performance of ISCG and
FCG. For the purposes of its opinion, Hambrecht & Quist also assumed that
neither FCG nor ISCG was a party to any pending transactions, including external
financings (other than those contemplated that have been disclosed to Hambrecht
& Quist), recapitalizations or merger discussions, other than the Merger and
those in the ordinary course of conducting their respective businesses. For
purposes of its opinion, Hambrecht & Quist assumed that the Merger will qualify
as a tax-free reorganization under the Internal Revenue Code of 1986, as amended
(the
 
                                       50
<PAGE>
"Code") for the shareholders of ISCG and that the Merger will be accounted for
as a pooling of interests. Hambrecht & Quist's opinion is necessarily based upon
market, economic, financial and other conditions as they existed and can be
evaluated as of the date of the opinion and any subsequent change in such
conditions would require a reevaluation of such opinion.
 
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The summary
of the Hambrecht & Quist analysis set forth below does not purport to be a
complete description of the presentation by Hambrecht & Quist to the FCG Board
of Directors. In arriving at its opinion, Hambrecht & Quist did not attribute
any particular weight to any analyses or factors considered by it, but rather
made qualitative judgments as to the significance and relevance of each analysis
and factor. Accordingly, Hambrecht & Quist believes that its analyses and the
summary set forth below must be considered as a whole and that selecting
portions of its analyses, without considering all analyses, or of the following
summary, without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the
Hambrecht & Quist presentation to the FCG Board of Directors and its opinion. In
performing its analyses, Hambrecht & Quist made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of FCG and ISCG. The
analyses performed by Hambrecht & Quist (and summarized below) are not
necessarily indicative of actual values or actual future results, which may be
significantly more or less favorable than suggested by such analyses.
Additionally, analyses relating to the values of businesses do not purport to be
appraisals or to reflect the prices at which businesses actually may be
acquired.
 
    In performing its analysis, Hambrecht & Quist used published Hambrecht &
Quist research estimates for projections of FCG's calendar year 1998 and 1999
financial performance. Hambrecht & Quist used published Baird research estimates
for projections of ISCG's calendar year 1998 and 1999 financial performance.
 
    The following is a brief summary of certain financial analyses performed by
Hambrecht & Quist in connection with providing its written opinion to the FCG
Board of Directors on September 9, 1998:
 
    CONTRIBUTION ANALYSIS.  Hambrecht & Quist analyzed the contribution of each
of FCG and ISCG to certain calendar 1998 and 1999 financial statement categories
of the pro forma Combined Company using published research estimates for both
companies with no revenue or expense adjustments. The financial statement
categories included revenue, operating income, and pretax income. This
contribution analysis was then compared to the pro forma ownership percentage of
FCG stockholders and ISCG shareholders in the pro forma post-merger Combined
Company. Hambrecht & Quist observed that, calculated on a treasury share basis,
FCG stockholders are expected to own approximately 70% of the Combined Company
equity at the close of the Merger and ISCG shareholders are expected to own
approximately 30% of the Combined Company equity at the close of the Merger. It
was estimated that FCG and ISCG would contribute approximately 67% and 33%,
respectively, of the combined revenues, approximately 61% and 39%, respectively,
of the combined operating income and approximately 64% and 36%, respectively, of
the combined pretax income in calendar 1998. It was estimated that FCG and ISCG
would contribute approximately 64% and 36%, respectively, of the combined
revenue, approximately 57% and 43%, respectively, of the combined operating
income and approximately 60% and 40%, respectively, of the combined pretax
income in calendar year 1999.
 
    PRO FORMA MERGER ANALYSIS.  Hambrecht & Quist analyzed the pro forma impact
of the Merger on the Combined Company's calendar 1998 and 1999 earnings per
share ("EPS") using published research for both companies. Hambrecht & Quist
observed that this resulted in greater EPS for the Combined Company than for FCG
on a stand-alone basis. The foregoing analysis did not assume any adjustments in
revenues or costs resulting from the operating synergies potentially realized
from the Merger. The actual results and savings achieved by the Combined Company
resulting from the Merger may vary from the projected results and variations may
be material.
 
                                       51
<PAGE>
    ANALYSIS OF PUBLICLY TRADED COMPARABLE COMPANIES.  Hambrecht & Quist
compared selected historical and projected financial information of ISCG to
publicly traded information technology ("IT") staff augmentation and to publicly
traded IT consulting companies Hambrecht & Quist deemed to be comparable to
ISCG. Such information included the ratio of market value to projected net
income and historical book value. Hambrecht & Quist also examined the ratio of
the enterprise value (market value plus debt less cash) to historical EBITDA and
EBIT. IT staff augmentation companies deemed comparable were Alternative
Resources Corp., Analysts International Corp., Complete Business Solutions,
Inc., Computer Horizons Corp., Computer Management Sciences, Inc., Cotelligent
Group, Inc., Data Processing Resources Corp., Hall Kinion & Associates, Inc.,
Mastech Corp., PRT Group, Inc., Renaissance Worldwide, Inc., Syntel, Inc., Tier
Technologies, Inc. and Ubics, Inc. IT consulting companies deemed comparable
were American Management Systems, Inc., Analysis & Technology, Inc., Cambridge
Technology Partners, Inc., Ciber, Inc., Diamond Technology Partners, Inc.,
ECsoft Group, plc, Exponent, Inc., First Consulting Group, Inc., Metzler Group,
Inc., Sapient Corp., Superior Consultant Holdings Corp. and Technology Solutions
Company. The foregoing multiples were applied to historical financial results of
ISCG for the LTM period ended June 30, 1998 and projected net income for
calendar 1998 and 1999 based on published Baird research estimates. Hambrecht &
Quist determined mean values for the IT staff augmentation companies of 1.8
times LTM revenue, 13.2 times LTM EBITDA, 14.8 times LTM EBIT, 21.1 times
projected calendar 1998 net income, 16.1 times projected calendar 1999 net
income, and 4.1 times book value. Based on the analysis of comparable IT staff
augmentation companies, ISCG's implied equity value per share ranged from $9.95
to $12.30. Hambrecht & Quist determined mean values for the IT consulting
companies of 3.4 times LTM revenue, 23.5 times LTM EBITDA, 28.9 times LTM EBIT,
30.6 times projected calendar 1998 net income, 24.4 times projected calendar
1999 net income, and 5.6 times book value. Based on the analysis of comparable
IT consulting companies, ISCG's implied equity value per share ranged from
$14.58 to $21.04. Each implied equity value range compared with an offer in the
proposed merger of approximately $13.67 per share based on the Exchange Ratio of
0.77 and closing price of FCG Common Stock on September 3, 1998 of $17.75.
 
    ANALYSIS OF SELECTED MERGER AND ACQUISITION TRANSACTIONS.  Hambrecht & Quist
compared the proposed merger with selected merger and acquisition transactions.
This analysis included 32 transactions involving companies in the consulting and
information services industry ("Comparable M&A Transactions"). In examining
these transactions, Hambrecht & Quist analyzed certain income statement and
balance sheet parameters of the acquired company relative to the consideration
offered. The foregoing multiples were applied to historical financial results of
ISCG for the twelve-month period ended June 30, 1998. Multiples analyzed
included consideration offered to LTM revenue, LTM EBITDA, LTM EBIT, LTM net
income, and book value. The mean multiples offered in the selected Comparable
M&A Transactions was 2.3 times LTM revenues, 28.6 times LTM EBITDA, 28.7 times
LTM EBIT, 47.6 times LTM net income, and 11.6 times book value. Based on the
analysis of selected Comparable M&A Transactions, ISCG's implied equity value
applying multiples to historical results ranged from values between $12.97 and
$30.32 per share. This compared with an offer in the proposed merger of
approximately $13.67 per share based on the Exchange Ratio of 0.77 and closing
price of FCG Common Stock on September 3, 1998 of $17.75.
 
    No company or transaction used in the above analyses is identical to ISCG or
the Merger. Accordingly, an analysis of the results of the foregoing is not
mathematical; rather it involves complex considerations and judgments concerning
differences in financial and operating characteristics of the companies and
other factors that could affect the public trading values of the companies or
company to which they are compared.
 
    PREMIUM ANALYSIS.  Hambrecht & Quist compared the implied premium of the
offer as of September 3, 1998 to similar premiums for the seven relevant
Comparable M&A Transactions. Hambrecht & Quist observed that the mean one-day
premium paid in the selected public company transactions was 36%. This compared
with the proposed acquisition in which, as of September 3, 1998, represented a
premium over the closing price for ISCG Common Stock of 38%. Hambrecht & Quist
also analyzed the implied
 
                                       52
<PAGE>
premiums to mean historical closing prices for the one week, one month and three
months ending September 3, 1998 using the implied offer price based on the 0.77
Exchange Ratio and found that the implied premiums were 28%, 53% and 48%,
respectively.
 
    DISCOUNTED CASH FLOW ANALYSIS.  Hambrecht & Quist performed discounted cash
flow analyses for ISCG using published research estimates for calendar 1998 and
1999 and ISCG management projections as adjusted by FCG management for calendar
2000 through 2002. The analysis aggregated (i) the present value of the
projected free cash flow (defined as after-tax EBIT, less increases in working
capital, plus depreciation and amortization, and less capital expenditures)
through 2002, (ii) the present value of a range of terminal values for the year
2002, and (iii) the combined value of debt and cash on the balance sheet of ISCG
as of August 1998. The terminal values for ISCG were determined by applying
multiples ranging from 1.5 to 2.5 times ISCG's estimated revenue for 2002.
ISCG's free cash flow streams and terminal values were discounted to present
values using discount rates ranging from 16% to 20%. Such analyses indicated a
range of equity values for ISCG of between $15.24 and $28.13 per share. This
compared with an offer in the proposed merger of approximately $13.67 per share
based on the Exchange Ratio of 0.77 and closing price of FCG Common Stock on
September 3, 1998 of $17.75.
 
    The foregoing description of Hambrecht & Quist's opinion is qualified in its
entirety by reference to the full text of such opinion which is attached as
Appendix B-2 to this Joint Proxy Statement/Prospectus.
 
    Hambrecht & Quist, as part of its investment banking services, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, strategic transactions, corporate restructurings,
negotiated underwriting, secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.
In the past, Hambrecht & Quist has provided investment banking and other
financial advisory services to FCG and has received fees for rendering these
services. In particular, Hambrecht & Quist acted as lead underwriter of FCG's
initial public offering on February 13, 1998, and received a fee for these
services. In the ordinary course of business, Hambrecht & Quist acts as a market
maker and broker in the publicly traded securities of FCG and receives customary
compensation in connection therewith, and also provides research coverage for
FCG. In the ordinary course of business, Hambrecht & Quist actively trades in
the equity and derivative securities of FCG for its own account and for the
accounts of its customers and, accordingly, may at any time hold a long or short
position in such securities. Hambrecht & Quist may in the future provide
additional investment banking or other financial advisory services to FCG.
 
    COMPENSATION.  Pursuant to an engagement letter dated June 29, 1998, FCG has
agreed to pay Hambrecht & Quist a fee of $250,000 in connection with the
delivery of the fairness opinion rendered on September 9, 1998. Upon
consummation of the Merger, FCG has agreed to pay Hambrecht & Quist a fee of
0.9% of the aggregate consideration paid in the transaction, less any fees
previously paid. FCG also has agreed to reimburse Hambrecht & Quist for its
reasonable out-of-pocket expenses and to indemnify Hambrecht & Quist against
certain liabilities, including liabilities under the federal securities laws or
relating to or arising out of Hambrecht & Quist's engagement as financial
advisor.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
    Certain members of ISCG's management and the ISCG Board of Directors may be
deemed to have certain interests in the Merger that are in addition to their
interests as shareholders of ISCG generally. The ISCG Board of Directors was
aware of these interests and considered them, among other matters, in approving
the Reorganization Agreement and the transactions contemplated thereby.
 
    INDEMNIFICATION AND INSURANCE.  The Reorganization Agreement provides that
all rights to indemnification existing in favor of the persons serving as
directors and officers of ISCG as of the date of the Reorganization Agreement
for acts or omissions occurring prior to the Effective Time, as provided in the
ISCG Bylaws and in any indemnification agreements between ISCG and such
directors and officers, will
 
                                       53
<PAGE>
   
survive the Merger, and that FCG will cause ISCG (the "Surviving Corporation")
to perform its obligations arising thereunder for at least six years from the
Effective Time. Subject to certain limitations, FCG has also agreed to cause the
Surviving Corporation to maintain in effect for three years after the Effective
Time a policy of directors' and officers' liability insurance for the benefit of
persons serving as directors and officers of ISCG as of such --ate. See "The
Reorganization Agreement]Covenants-- Indemnification and Insurance."
    
 
    NOMINATION AND APPOINTMENT OF DIRECTORS.  As soon as practicable after the
Effective Time, FCG shall use reasonable efforts to nominate and appoint (i)
Warren V. Musser, or such other nominee designated by ISCG, to Class I of the
FCG Board of Directors to serve until the annual meeting of stockholders to be
held in 1999 and (ii) David S. Lipson, or such other nominee designated by ISCG,
to Class II of the FCG Board of Directors to serve until the annual meeting of
stockholders to be held in 2000.
 
VOTING AGREEMENTS
 
    ISCG VOTING AGREEMENTS.  Pursuant to the ISCG Voting Agreements, the ISCG
Voting Agreement Shareholders, who beneficially own an aggregate of 5,253,996
outstanding shares of ISCG Common Stock (representing approximately 60.0% of the
shares of ISCG Common Stock as of September 9, 1998) have agreed that, prior to
the Expiration Date, they will vote their shares of ISCG Common Stock in favor
of: (i) approval and adoption of the Reorganization Agreement; (ii) approval of
the Merger; and (iii) each of the other actions contemplated by the
Reorganization Agreement. The ISCG Voting Agreement Shareholders have also
delivered to FCG irrevocable proxies with respect to the matters covered by the
ISCG Voting Agreements. In addition, the ISCG Voting Agreement Shareholders have
agreed not to transfer any securities of ISCG owned by them unless and until the
proposed transferee of such ISCG securities shall have (i) executed a
counterpart of the ISCG Voting Agreement and an irrevocable proxy and (ii)
agreed to hold such ISCG securities subject to all of the terms and provisions
of the ISCG Voting Agreement. The affirmative vote of the shares of ISCG Common
Stock subject to the ISCG Voting Agreements will be sufficient to approve and
adopt the Reorganization Agreement and to approve the Merger. The form of ISCG
Voting Agreement is attached to this Joint Proxy Statement/Prospectus as
Appendix C-1.
 
    FCG VOTING AGREEMENTS.  Pursuant to the FCG Voting Agreements, the FCG
Voting Agreement Stockholders, who beneficially own an aggregate of 4,339,072
outstanding shares of FCG Common Stock (representing approximately 27.3% of the
shares of FCG Common Stock as of September 9,1998) have agreed that, prior to
the Expiration Date, they will vote their shares of FCG Common Stock in favor of
(i) the issuance of the shares of FCG Common Stock to be issued in the Merger
and (ii) each of the other actions contemplated by the Reorganization Agreement.
The FCG Voting Agreement Stockholders have also delivered to ISCG irrevocable
proxies with respect to the matters covered by the FCG Voting Agreements. In
addition, the FCG Voting Agreement Stockholders have also agreed, in certain
instances, to require any party to whom their shares of FCG Common Stock may be
sold, pledged, granted an option to purchase, or otherwise transferred to
execute a counterpart of the FCG Voting Agreement and agree to hold such FCG
securities subject to all the terms and provisions of the FCG Voting Agreements.
The form of FCG Voting Agreement is attached to this Joint Proxy
Statement/Prospectus as Appendix C-2.
 
AFFILIATE AGREEMENTS
 
   
    ISCG AFFILIATE AGREEMENTS.  Pursuant to certain agreements (each an "ISCG
Affiliate Agreement"), certain individuals and entities that may be deemed
affiliate of ISCG (each, an "ISCG Affiliate") have agreed not to effect any
sale, transfer or other disposition of the FCG Common Stock received by such
ISCG Affiliate in the Merger unless: (i) such sale, transfer or other
disposition is made in conformity with the volume and other requirements of Rule
145 under the Securities Act of 1933, as amended (the "Securities Act"), as
evidenced by a broker's letter and a representation letter executed by the ISCG
Affiliate (reasonably satisfactory in form and content to FCG), each stating
that such requirements have
    
 
                                       54
<PAGE>
been met; (ii) legal counsel reasonably satisfactory to FCG shall have advised
FCG in a written opinion letter (reasonably satisfactory in form and content to
FCG), upon which FCG may rely, that such sale, transfer or other disposition
will be exempt from registration under the Securities Act; (iii) such sale,
transfer or other disposition is effected pursuant to an effective registration
statement under the Securities Act; or (iv) an authorized representative of the
Commission shall have rendered written advice to such ISCG Affiliate to the
effect that the Commission would take no action, or that the staff of the
Commission would not recommend that the Commission take action, with respect to
such proposed sale, transfer or other disposition, and a copy of such written
advice and all other related communications with the Commission shall have been
delivered to FCG.
 
    In addition, so as to help ensure that the Merger will be treated as a
pooling of interests for accounting and financial reporting purposes, the ISCG
Affiliate Agreements provide that during the period contemplated by the
Commission's Staff Accounting Bulletin Number 65 until the earlier of (i) FCG's
public announcement of financial results covering at least 30 days of combined
operations of FCG and ISCG or (ii) the Reorganization Agreement is terminated in
accordance with its terms, no ISCG Affiliate shall sell, exchange, transfer,
pledge, distribute or otherwise dispose of or grant any option, establish any
"short" or put-equivalent position with respect to or enter into any similar
transaction (through derivatives or otherwise) intended or having the effect,
directly or indirectly, to reduce such ISCG Affiliate's risk relative to: (i)
any ISCG Common Stock (except pursuant to and upon consummation of the Merger);
or (ii) any FCG Common Stock received by such ISCG Affiliate in the Merger or
upon exercise of options assumed by FCG in the Merger. Provided certain
conditions are met, the ISCG Affiliate Agreements provide for certain exceptions
to the foregoing restrictions on transfer relating to: (i) certain DE MINIMIS
transfers; (ii) transfers in payment of the exercise price of options to
purchase ISCG Common Stock or FCG Common Stock; (iii) charitable donations; and
(iv) transfers to trusts established for the benefit of members of such ISCG
Affiliate's family or gifts to members of such ISCG Affiliate's family. The form
of ISCG Affiliate Agreement is attached to this Joint Proxy Statement/Prospectus
as Appendix D-1.
 
   
    FCG AFFILIATE AGREEMENTS.  Pursuant to certain agreements (each an "FCG
Affiliate Agreement" and, collectively, the "FCG Affiliate Agreements"), certain
individuals and entities that may be deemed affiliates of FCG (each, an "FCG
Affiliate") have agreed that, during the period contemplated by the Commission's
Staff Accounting Bulletin Number 65 until the earlier of (i) FCG's public
announcement of financial results covering at least 30 days of combined
operations of FCG and ISCG or (ii) the Reorganization Agreement is terminated in
accordance with its terms, such FCG Affiliate shall not, subject to certain
exceptions, sell, exchange, transfer, pledge, distribute or otherwise dispose of
or grant any option, establish any "short" or put-equivalent position with
respect to or enter into any similar transaction (through derivative's or
otherwise) intended or having the effect, directly or indirectly, to reduce such
FCG Affiliate's risk relative to any FCG Common Stock. Provided certain
conditions are met, the FCG Affiliate Agreements provide for certain exceptions
to the foregoing restrictions on transfer relating to: (i) certain DE MINIMIS
transfers; (ii) transfers in payment of the exercise price of options to
purchase FCG Common Stock; (iii) charitable donations; or (iv) transfers to
trusts established for the benefit of members of such FCG Affiliate's family or
gifts to members of such FCG Affiliate's family. The form of the FCG Affiliate
Agreement is attached to this Joint Proxy Statement/Prospectus as Appendix D-2.
    
 
REGISTRATION RIGHTS AGREEMENT
 
   
    Upon the consummation of the transactions contemplated by the Reorganization
Agreement, which will occur on a date to be agreed by FCG and ISCG (the "Closing
Date"), certain holders of ISCG stock, consisting of David S. Lipson, Technology
Leaders II, Safeguard Scientifics, Inc. and the Warrant and Stock Trust
(collectively the "Holders"), will be entitled to certain rights with respect to
the registration of their shares of FCG Common Stock issued in connection with
the Merger under the Securities Act. Under the terms of the Registration Rights
Agreement, which ISCG has agreed to deliver on the Closing Date, if FCG proposes
to register any of its securities under the Securities Act for purposes of
distributing
    
 
                                       55
<PAGE>
securities of FCG by means of an underwritten public offering, the Holders are
entitled to notice of such registration and are entitled to include their shares
of stock, provided, among other conditions, that the underwriters of any
offering have the right to limit the number of shares included in such
registration or exclude such shares entirely. In addition, subject to certain
conditions, the Holders may also require FCG, beginning on the date of FCG's
public announcement of financial results covering at least 30 days of combined
operations of FCG and ISCG, and expiring 18 months from the date of the
Registration Rights Agreement, on not more than one occasion, to file a
registration statement under the Securities Act at FCG's expense (other than
underwriting discounts and commissions) with respect to the shares owned by the
Holders, which amount may be reduced by shares owned by other holders of
registration rights; provided, further, that the number of shares allocated to
the Holders shall not be less than 2,000,000 shares unless the aggregate number
of shares to be registered is less than 2,000,000, in which case all shares to
be registered shall be allocated to the Holders. The form of the Registration
Rights Agreement is attached to this Joint Proxy Statement/Prospectus as
Appendix E.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
    The following discussion summarizes the material federal income tax
considerations of the Merger that are generally applicable to holders of ISCG
Common Stock. This discussion assumes that holders of ISCG Common Stock hold
such shares as capital assets. This discussion is based on currently existing
provisions of the Code, existing and proposed Treasury Regulations thereunder
and current administrative rulings and court decisions, all of which are subject
to change. Any such change, which may or may not be retroactive, could alter the
tax consequences to FCG, ISCG or the ISCG shareholders as described herein.
 
    ISCG shareholders should be aware that this discussion does not deal with
all U.S. federal income tax considerations that may be relevant to particular
ISCG shareholders in light of their particular circumstances, such as
shareholders who are dealers in securities, banks, insurance companies or
tax-exempt organizations, who are subject to the alternative minimum tax
provisions of the Code, who are non-United States persons, who acquired their
shares in connection with stock option or stock purchase plans or in other
compensatory transactions or who hold their shares as a hedge or as part of a
hedging, straddle, conversion or other risk reduction transaction. In addition,
the following discussion does not address the tax consequences of the Merger
under foreign, state or local tax laws or the tax consequences of transactions
effectuated prior to or after the Merger (whether or not such transactions are
in connection with the Merger).
 
    It is the opinion of Saul Ewing and Cooley Godward that the Merger will
constitute a reorganization (a "Reorganization") pursuant to Section 368(a) of
the Code (collectively, the "Tax Opinions"). In addition, ISCG's obligation to
consummate the Merger is conditioned on the receipt by ISCG of an opinion from
Saul Ewing, and FCG's and Merger Sub's obligations to consummate the Merger are
conditioned on their receipt of an opinion from Cooley Godward, confirming that
the Merger will constitute a Reorganization (collectively, the "Closing
Opinions"). Such conditions will not be waived without a resolicitation of
consent by the shareholders of ISCG and stockholders of FCG. Saul Ewing and
Cooley Godward have advised ISCG, and FCG and Merger Sub, respectively, that
they currently expect to be able to deliver such Closing Opinions. See "The
Reorganization Agreement--Conditions to the Merger--FCG and Merger Sub" and
"--ISCG." The Tax Opinions and Closing Opinions (i) will not be binding on the
IRS nor preclude the IRS from adopting a contrary position, (ii) will be based
on the assumptions discussed below, as well as representations received from
ISCG, FCG and Merger Sub, (iii) will be based on the assumption that the Merger
will be consummated in accordance with the terms of the Reorganization Agreement
and (iv) will be subject to the limitations discussed below. Neither ISCG nor
FCG has requested, or will request, a ruling from the IRS with regard to any of
the federal income tax consequences of the Merger. The Tax Opinions and Closing
Opinions assume and are conditioned upon (i) the truth and accuracy of the
statements, covenants, representations and warranties contained in the
Reorganization Agreement, in the representations received from ISCG, FCG and
Merger Sub to support the Tax Opinions and Closing Opinions (the "Tax
Representations") and in all other instruments and
 
                                       56
<PAGE>
documents related to the formation, organization and operation of ISCG, FCG and
Merger Sub examined by and relied upon by Saul Ewing and Cooley Godward in
connection with the Merger; (ii) that original documents submitted to such
counsel (including signatures thereto) are authentic, documents submitted to
such counsel as copies conform to the original documents, and that all such
documents have been (or will be by the Effective Time) duly and validly executed
and delivered where due execution and delivery are a prerequisite to the
effectiveness thereof; (iii) that all covenants contained in the Reorganization
Agreement (including exhibits thereto) and in the Tax Representations are
performed without waiver or breach of any material provision thereof; (iv) that
the Merger will be reported by FCG and ISCG on their respective federal income
tax returns in a manner consistent with the Tax Opinions and the Closing
Opinions; and (v) that any representation or statement made "to the best of
knowledge" or similarly qualified is correct without such qualification.
 
    Subject to the limitations and qualifications referred to herein and in the
Tax Opinions and Closing Opinions, it is the opinion of Saul Ewing and Cooley
Godward that as a result of the Merger's qualifying as a Reorganization, the
following U.S. federal income tax consequences will result:
 
        (i) No gain or loss will be recognized for federal income tax purposes
    by the holders of ISCG Common Stock upon the receipt of FCG Common Stock
    solely in exchange for such ISCG Common Stock in the Merger (except to the
    extent, if any, of cash received in lieu of fractional shares);
 
        (ii) The aggregate tax basis of the FCG Common Stock so received by each
    ISCG shareholder in the Merger (including any fractional share of FCG Common
    Stock not actually received) will be the same as the aggregate tax basis of
    ISCG Common Stock surrendered by such ISCG shareholder in exchange therefor;
 
       (iii) The holding period of FCG Common Stock so received by each ISCG
    shareholder in the Merger will include the period for which ISCG Common
    Stock surrendered in exchange therefor was considered to be held, provided
    that ISCG Common Stock so surrendered is held as a capital asset at the
    Effective Time;
 
        (iv) Cash payments received by holders of ISCG Common Stock in lieu of a
    fractional share will be treated as if such fractional share of FCG Common
    Stock had been issued in the Merger and then redeemed by FCG. An ISCG
    shareholder receiving such cash will recognize gain or loss upon such
    payment, measured by the difference (if any) between the amount of cash
    received and the basis in such fractional share. The gain or loss should be
    capital gain or loss provided that each such fractional share of ISCG Common
    Stock was held as a capital asset at the Effective Time;
 
        (v) A shareholder of ISCG who properly exercises dissenters' rights
    under any applicable law with respect to a share of ISCG Common Stock and
    receives payments for such stock in cash should recognize capital gain or
    loss (if such stock was held as a capital asset at the Effective Time of the
    Merger) measured by the difference between the amount of cash received and
    the shareholder's basis in such share, provided such payment is neither
    essentially equivalent to a dividend within the meaning of Section 302 of
    the Code nor has the effect of a distribution of a dividend within the
    meaning of Section 356(a)(2) of the Code (collectively, a "Dividend
    Equivalent Transaction"). A sale of ISCG shares incident to an exercise of
    dissenters' rights will generally not be a Dividend Equivalent Transaction
    if, as a result of such exercise, the dissenting shareholder owns no shares
    of FCG Common Stock (either actually or constructively within the meaning of
    Section 318 of the Code) immediately after the Merger; and
 
        (vi) Neither FCG nor ISCG will recognize gain solely as a result of the
    Merger.
 
    A successful IRS challenge to the Reorganization status of the Merger would
result in significant adverse tax consequences to the ISCG shareholders. An ISCG
shareholder would recognize gain or loss with respect to each share of ISCG
Common Stock surrendered equal to the difference between the shareholder's basis
in such share and the fair market value, as of the Effective Time, of the FCG
Common Stock received in exchange therefor. In such event, a shareholder's
aggregate basis in the FCG Common
 
                                       57
<PAGE>
Stock so received would equal its fair market value, and the shareholder's
holding period for such stock would begin the day after the Closing Date.
 
    Even if the Merger qualifies as a Reorganization, a recipient of FCG Common
Stock would recognize income to the extent that, for example, any such shares
were determined to have been received in exchange for services, to satisfy
obligations or in consideration for anything other than the ISCG Common Stock
surrendered. In addition, to the extent that an ISCG shareholder were treated as
receiving (directly or indirectly) consideration other than FCG Common Stock in
exchange for such shareholder's ISCG Common Stock, gain, if any, would have to
be recognized.
 
    Certain noncorporate ISCG shareholders may be subject to backup withholding
at a rate of 31% on cash payments received in lieu of a fractional share
interest in FCG Common Stock. Backup withholding will not apply, however, to a
shareholder who furnishes a correct taxpayer identification number ("TIN") and
certifies that he, she or it is not subject to backup withholding on the
substitute Form W-9 included in the letter of transmittal, who provides a
certificate of foreign status on Form W-8, or who is otherwise exempt from
backup withholding. A shareholder who fails to provide the correct TIN on Form
W-9 may be subject to a $50 penalty imposed by the IRS.
 
   
    THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO THE MERGER. THUS, HOLDERS OF
ISCG COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC
TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING
REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL AND OTHER
APPLICABLE TAX LAWS AND THE EFFECTS OF ANY PROPOSED CHANGES IN THE TAX LAWS.
    
 
    Each ISCG shareholder will be required to retain records and file with such
shareholder's U.S. federal income tax return a statement setting forth certain
facts relating to the Merger.
 
ANTICIPATED ACCOUNTING TREATMENT
 
    The Merger is intended to qualify as a pooling of interests for financial
reporting purposes in accordance with GAAP. This accounting method would permit
the recorded assets and liabilities of ISCG to be carried forward to the
consolidated financial statements of FCG at their recorded historical amounts.
Consummation of the Merger is conditioned upon (i) the receipt by FCG of a
letter from its independent accountants dated as of the Closing Date to the
effect that such accountants concur with FCG management's conclusion that
pooling of interests accounting for the Merger is appropriate, and (ii) receipt
by ISCG of a letter from its independent accountants dated as of a date no
earlier than the date three days prior to the Effective Time to the effect that
such accountants concur with ISCG management's conclusion that no conditions
exist relating to ISCG that would preclude FCG from accounting for the Merger as
a pooling of interests.
 
REGULATORY MATTERS
 
   
    ANTITRUST.  The Merger is not subject to the premerger notification
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended (the "HSR Act"). However, the FTC or the Antitrust Division of the
United States Department of Justice (the "Antitrust Division") could take such
action under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin consummation of the Merger or seeking to
cause divestiture of significant assets of FCG or ISCG or their subsidiaries.
There can be no assurance that a challenge to the Merger on antitrust grounds
will not be made, or, if such challenge is made, of what the result would be.
Consummation of the Merger is conditioned upon, among other things, the absence
of any temporary restraining order, preliminary or permanent injunction, or
other order issued by any federal or state court in the United States which
prevents the consummation of the Merger.
    
 
    FILINGS WITH THE SECRETARY OF STATE OF THE COMMONWEALTH OF PENNSYLVANIA AND
THE SECRETARY OF STATE OF THE STATE OF DELAWARE.  Articles of Merger must be
filed with the Secretary of State of the Commonwealth of
 
                                       58
<PAGE>
Pennsylvania and a Certificate of Merger must be filed with the Secretary of
State of Delaware to consummate the Merger.
 
RIGHTS OF DISSENTING SHAREHOLDERS OF ISCG
 
    Pursuant to the PBCL, shareholders of ISCG have the right to dissent from
the Merger, and to obtain payment of the "fair value" (as defined in the PBCL)
of their shares, if the Merger is consummated. The term "fair value" means the
fair value of the shares immediately before completion of the Merger, taking
into account all relevant factors, but excluding any appreciation or
depreciation in anticipation of the Merger.
 
    The following summary of the steps to be taken if the right to dissent is to
be exercised is qualified in its entirety by the full text of Section 1930 and
Subchapter D of Chapter 15 of the PBCL, which are attached to this Joint Proxy
Statement/Prospectus as Appendix F. Each step must be taken in the indicated
order and in strict compliance with the applicable provisions of the statute in
order to perfect dissenters' rights. The failure of any shareholder to comply
with these steps will result in the shareholder receiving the consideration
contemplated by the Reorganization Agreement and waiving his right to dissent.
Any shareholder of ISCG who contemplates exercising the right to dissent is
urged to read carefully the provisions of Section 1930 and Subchapter D of
Chapter 15 of the PBCL.
 
    Any written notice or demand which is required in connection with the
exercise of dissenters' rights, whether before or after the Effective Time, may
be sent to ISCG at the ISCG Principal Offices.
 
    A shareholder who wishes to dissent must file with ISCG prior to the vote of
shareholders on the Merger at the ISCG Special Meeting, a written notice of
intention to demand that he be paid the fair value for his shares, if the Merger
is effected, must effect no change in the beneficial ownership of his shares
from the date of such filing continuously through the Closing Date, and must
refrain from voting his shares to approve the Merger. Neither a proxy nor a vote
against approval of the Merger will constitute the necessary written notice of
intention to dissent. A beneficial owner of shares which are held of record in
"street name" by a brokerage firm or other nominee must obtain the written
consent of such record holder to such beneficial owner's exercise of dissenters'
rights and must submit such consent to ISCG, no later than the time of the
filing of his notice of intention to dissent.
 
    If the Merger is approved by the required vote of ISCG's shareholders at the
ISCG Special Meeting, ISCG will mail a notice to all dissenters who gave due
notice of intention to demand payment of their shares and who refrained from
voting in favor of the Merger. The notice will state where and when a demand for
payment must be sent and certificates for the shares must be deposited in order
to obtain payment, and will include a form for demanding payment and a copy of
Subchapter D of Chapter 15 of the PBCL. The time set for receipt of the demand
for payment and deposit of stock certificates will not be less than 30 days from
the date of mailing of the notice.
 
    A shareholder who fails to timely demand payment or fails to timely deposit
stock certificates, as required by ISCG's notice, will not have any right to
receive payment of the fair value of his shares.
 
    Promptly after completion of the Merger, or upon timely receipt of demand
for payment if the Merger already has been completed, ISCG will either remit to
dissenters who have made demand and have deposited their stock certificates the
amount that ISCG estimates to be the fair value of such dissenters' shares or
give written notice that no such remittance is being made. The remittance or
notice will be accompanied by (i) a closing balance sheet and an income
statement of ISCG for a fiscal year ending not more than 16 months before the
date of remittance or notice, together with the latest available interim
financial statements, (ii) a statement of ISCG's estimate of the fair value of
the shares, and (iii) notice of the right of the dissenter to demand payment or
supplemental payment under the PBCL, as the case may be, accompanied by a copy
of Subchapter D of Chapter 15 of the PBCL. If ISCG does not remit the amount of
its estimated fair value for shares with respect to which demand for payment has
been made and stock certificates have been deposited, then ISCG will return any
certificates that have been deposited.
 
                                       59
<PAGE>
Returned certificates, and any certificates subsequently issued in exchange
therefor, will be marked to record the fact that demand for payment has been
made. Transferees of shares so marked shall not acquire any rights in ISCG other
than those rights held by the original dissenter after such dissenter demanded
payment of fair value.
 
    If a dissenter believes that the amount stated in the notice as ISCG's
estimate of the fair value of the dissenters' shares or remitted by ISCG is less
than the fair value of the dissenters' shares, he may send ISCG his own estimate
of the fair value of such shares, which shall be deemed to be a demand for
payment of the amount of the deficiency. If ISCG remits payment of its estimated
value of a dissenter's shares or delivers notice of its estimate of the fair
value of the dissenters' shares, and the dissenter does not file his own
estimate within 30 days after the mailing by ISCG of its remittance or notice,
the dissenter will be entitled to no more than the amount stated in the notice
or remitted to him by ISCG.
 
    Within 60 days after the latest to occur of completion of the Merger, timely
receipt by ISCG of any demands for payment, or timely receipt by ISCG, as the
case may be, of any estimates by dissenters of fair value, if any demands for
payment remain unsettled, ISCG may file in the Court of Common Pleas of Chester
County (the "Court"), an application requesting that the fair value of the
dissenters' shares be determined by the Court. In such case, all dissenters,
wherever residing, whose demands have not been settled shall be made parties to
the proceeding as in an action against their shares, and a copy of the
application shall be served on each such dissenter. The Court may appoint an
appraiser to receive evidence and recommend a decision on the issue of fair
value. The appraiser shall have such power and authority as may be specified in
the order of appointment or in any amendment thereof. Each dissenter who is made
a party shall be entitled to recover the amount by which the fair value of his
shares is found to exceed the amount, if any, previously remitted, plus
interest. If ISCG were to fail to file such an application, then any dissenter
who has made a demand and who has not settled his claim against ISCG may file an
application in the name of ISCG at any time within 30-days after the expiration
of the 60-day period and request that the fair value be determined by the Court.
If no dissenter files such an application, then each dissenter entitled to do so
shall be paid ISCG's estimate of the fair value of the dissenters' shares and no
more, and may bring an action to recover any amount not previously remitted.
 
    If ISCG were to fail to file such an application, then any dissenter who has
made a demand and who has not settled his claim against ISCG may file an
application in the name of ISCG at any time within 30 days after the expiration
of the 60-day period and request that the fair value be determined by the Court.
If no dissenter files such an application, then each dissenter entitled to do so
shall be paid ISCG's estimate of the fair value of the dissenters' shares and no
more, and may bring an action to recover any amount not previously remitted.
 
    Holders of ISCG Common Stock considering exercising dissenters' rights
should recognize that the fair value of their shares determined by the Court
could be more than, the same as or less than the consideration they are entitled
to receive pursuant to the Reorganization Agreement if they do not exercise
dissenters' rights. The costs and expenses of valuation proceedings before the
Court, including the reasonable compensation and expenses of the appraiser
appointed by the Court, shall be determined by the Court and assessed against
the business corporation except that any part of the costs and expenses may be
apportioned and assessed as the Court deems appropriate against all or some of
the dissenters who are parties and whose action in demanding supplemental
payment the Court finds to be dilatory, obdurate, arbitrary, vexatious or in bad
faith. Fees and expenses of counsel and of experts for the respective parties
may be assessed as the Court deems appropriate against the corporation and in
favor of any or all dissenters if the corporation failed to comply substantially
with the requirements of this subchapter and may be assessed against either the
corporation or a dissenter, in favor of any other party, if the Court finds that
the party against whom the fees and expenses are assessed acted in bad faith or
in a dilatory, obdurate, arbitrary or vexatious manner in respect to the rights
provided by the PBCL. If the Court finds that the services of counsel for any
dissenter were of substantial benefit to other dissenters similarly situated and
 
                                       60
<PAGE>
should not be assessed against the corporation, it may award to those counsel
reasonable fees to be paid out of the amounts awarded to the dissenters who were
benefited.
 
    ISCG intends to negotiate in good faith with any dissenting shareholder. If
after negotiation, a claim cannot be settled, then ISCG intends to file an
application requesting that the fair value of the dissenters' shares be
determined by the Court.
 
NO FCG APPRAISAL RIGHTS
 
   
    Holders of FCG Common Stock are not entitled to appraisal rights under the
DGCL because FCG is not a constituent corporation to the Merger under the DGCL.
    
 
RESALE OF FCG COMMON STOCK
 
   
    FCG Common Stock issued in connection with the Merger will be freely
transferable, except that shares issued to an ISCG Affiliate or who becomes an
affiliate of FCG are subject to certain restrictions on resale. An affiliate is
defined generally as including, without limitation, directors, certain executive
officers and certain other persons who control a company. Pursuant to the terms
of the Reorganization Agreement, ISCG has delivered to FCG, ISCG Affiliate
Agreements executed by the ISCG Affiliates that prohibit the sale, exchange,
transfer, pledging, distribution or other disposition of or granting of any
option, establishment of any "short" or put-equivalent position with respect to
or any similar transaction (through derivatives or otherwise) intended or having
the effect, directly or indirectly, to reduce such ISCG Affiliate's risk
relative to: (i) any ISCG Common Stock (except pursuant to and upon consummation
of the Merger); or (ii) any FCG Common Stock received by such ISCG Affiliate in
the Merger or upon exercise of options assumed by FCG in the Merger, except
under certain circumstances, in order to comply with the requirements of certain
federal securities laws and to help ensure the Merger is treated as a pooling of
interest for accounting and financial reporting purposes. See "Approval of the
Merger and Related Transactions--Affiliate Agreements."
    
 
   
    Pursuant to the terms of the Reorganization Agreement, FCG has delivered to
ISCG FCG Affiliate Agreements executed by the FCG Affiliates that prohibit the
sale, exchange, transfer, pledging, distribution or other disposition of or
granting of any option, establishment of any "short" or put-equivalent position
with respect to or any similar transaction (through derivatives or otherwise)
intended or having the effect, directly or indirectly, to reduce such FCG
Affiliate's risk relative to any FCG Common Stock except under certain
circumstances, so as to help ensure that the Merger will be accounted for as a
pooling of interests. See "Approval of the Merger and Related
Transactions--Affiliate Agreements."
    
 
   
    Pursuant to the terms of the Reorganization Agreement, FCG has agreed to
enter into a registration rights agreement with David S. Lipson, Technology
Leaders II, Safeguard Scientifics, Inc. and the Warrant and Stock Trust (the
"Registration Rights Agreement") at the Closing, which grants the Holders
certain rights with respect to the registration under the Securities Act of

                          THE REORGANIZATION AGREEMENT
 
GENERAL
 
    The following is a summary of the material provisions of the Reorganization
Agreement, a copy of which is attached as Appendix A to this Joint Proxy
Statement/Prospectus and is incorporated herein by reference. However, the
following is not a complete statement of all provisions of the Reorganization
Agreement and related agreements. Statements made in this Joint Proxy
Statement/Prospectus with respect to the terms of the Reorganization Agreement
and such related agreements are qualified in their
 
                                       61
<PAGE>
respective entireties by reference to the more detailed information set forth in
the Reorganization Agreement and such related agreements. Capitalized terms used
in this summary but not defined in this Joint Proxy Statement/Prospectus shall
have the meanings ascribed to them in the Reorganization Agreement.
 
    The Reorganization Agreement provides for the merger of Merger Sub with and
into ISCG. As a result of the Merger, Merger Sub will cease to exist, ISCG will
become a wholly-owned subsidiary of FCG, and the former shareholders of ISCG
will become stockholders of FCG. ISCG, as the Surviving Corporation, will retain
all of its separate corporate existence, with all its purposes, objects, rights,
privileges, powers and franchises unaffected by the Merger. Merger Sub has been
formed solely for the purpose of effecting the Merger, and there will be no
other activity in Merger Sub. The Merger will become effective at the Effective
Time, which shall be upon the filing of Articles of Merger with the Secretary of
State of the Commonwealth of Pennsylvania and the Certificate of Merger with the
Secretary of State of the State of Delaware or such later time as may be
specified in the Articles of Merger. The Effective Time shall occur no later
than the second day after the satisfaction or waiver of all the conditions to
closing set forth in the Reorganization Agreement. It is currently anticipated
that the Effective Time will occur on or before [       ], 1998. There can be no
assurance, however, that the conditions to the Merger will be satisfied by such
date, or at all, or that the Reorganization Agreement will not be terminated.
See "--Conditions to the Merger."
 
MERGER CONSIDERATION
 
    ISCG COMMON STOCK.  At the Effective Time, each share of ISCG Common Stock
then outstanding will be converted into the right to receive FCG Common Stock
based on the Exchange Ratio. The Exchange Ratio is currently 0.77, which will be
adjusted for any subsequent stock split, stock dividend, reverse stock splits
reclassification, recapitalization or similar transaction.
 
   
    NO FRACTIONAL SHARES.  No fractional shares of FCG Common Stock will be
issued in connection with the Merger, and no certificates for any such
fractional shares will be issued. In lieu of such fractional shares, any holder
of ISCG Common Stock (after aggregating all fractional shares of FCG Common
Stock issuable to such shareholder) will, upon surrender of such shareholder's
stock certificate(s) representing ISCG Common Stock to the American Stock
Transfer & Trust Company, transfer agent and registrar for FCG Common Stock and
exchange agent for purposes of the Merger (the "Exchange Agent"), be paid in
cash the dollar amount (rounded to the nearest whole cent), without interest,
determined by multiplying such fraction by the closing price of a share of FCG
Common Stock on Nasdaq on the "Closing Date" (as defined herein).
    
 
STOCK OPTIONS AND WARRANTS
 
    STOCK OPTIONS.  At the Effective Time, all outstanding options with respect
to ISCG Common Stock under ISCG's Amended and Restated Option Plan
(collectively, "ISCG Options") shall be converted into and become rights with
respect to FCG Common Stock, and FCG shall assume each such option in accordance
with the terms (as in effect as of the date of the Reorganization Agreement) of
the stock option plan under which it was issued and the stock option agreement
by which it is evidenced. From and after the Effective Time, (i) each ISCG
Option assumed by FCG may be exercised solely for shares of FCG Common Stock,
(ii) the number of shares of FCG Common Stock subject to each such ISCG Option
shall be equal to the number of shares of ISCG Common Stock subject to such ISCG
Option immediately prior to the Effective Time multiplied by the Exchange Ratio,
rounding down to the nearest whole share (with cash, less the applicable
exercise price, being payable for any fraction of a share), (iii) the per share
exercise price under each such ISCG Option shall be adjusted by dividing the per
share exercise price under such ISCG Option by the Exchange Ratio and rounding
up to the nearest cent, and (iv) any restriction on the exercise of any such
ISCG Option shall continue in full force and effect and the term,
 
                                       62
<PAGE>
exercisability, vesting schedule and other provisions of such ISCG Option shall
otherwise remain unchanged.
 
    WARRANTS.  All rights with respect to ISCG Common Stock under warrants that
are then outstanding shall be converted into and become rights with respect to
FCG Common Stock, and FCG shall, subject to certain limitations, assume all such
warrants in accordance with the terms of such warrants. Each warrant assumed by
FCG (i) may be exercised solely for shares of FCG Common Stock, (ii) the number
of shares of FCG Common Stock subject to each warrant assumed shall be equal to
the number of shares of ISCG Common Stock subject to such warrant immediately
prior to the Effective Time multiplied by the Exchange Ratio, rounding down to
the nearest whole share (with cash, less the applicable exercise price, being
payable for any fraction of a share), (iii) the per share exercise price under
each warrant assumed shall be adjusted by dividing the per share exercise price
under the warrant by the Exchange Ratio and rounding up to the nearest cent (to
the extent permitted by the terms of the warrants and otherwise rounded or
without rounding as required by the terms of the particular warrant).
 
STOCK OWNERSHIP FOLLOWING THE MERGER
 
    Based upon the number of shares of ISCG Common Stock issued and outstanding
as of the ISCG Record Date, an aggregate of approximately          shares of FCG
Common Stock will be issued to security holders of ISCG. Based upon the number
of shares of FCG Common Stock issued and outstanding as of the FCG Record Date
(assuming no exercise of outstanding options, warrants or other rights to
purchase FCG Common Stock), the former holders of ISCG Common Stock would hold
and have voting power with respect to approximately    % of FCG's total issued
and outstanding shares after consummation of the Merger.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
   
    As soon as practicable after the Effective Time, the Exchange Agent will
mail to the registered holders of ISCG Common Stock (i) a letter of transmittal
and (ii) instructions for the use in effecting the surrender of valid
certificates representing shares of ISCG Common Stock (the "ISCG Stock
Certificates") in exchange for certificates representing FCG Common Stock. Upon
surrender of an ISCG Stock Certificate to the Exchange Agent for exchange,
together with a duly executed letter of transmittal and such other documents as
may reasonably be required by the Exchange Agent or FCG, the holder of such ISCG
Stock Certificate shall be entitled to receive in exchange therefor a
certificate representing the whole number of shares of FCG Common Stock that
such shareholder has the right to receive. No fractional shares of FCG Common
Stock will be issued in connection with the Merger, and no certificates for any
such fractional shares will be issued. See "--Merger Consideration--No
Fractional Shares."
    
 
    If any ISCG Stock Certificate has been lost, stolen or destroyed, FCG may
require the owner of such lost, stolen or destroyed ISCG Stock Certificate to
provide an appropriate affidavit and to deliver a bond as indemnity against any
claim that may be made against the Exchange Agent, FCG or ISCG with respect to
such ISCG Stock Certificate.
 
   
    ISCG SHAREHOLDERS SHOULD NOT SURRENDER THEIR ISCG STOCK CERTIFICATES FOR
EXCHANGE UNTIL THEY RECEIVE A LETTER OF TRANSMITTAL FROM THE EXCHANGE AGENT.
    
 
EFFECT ON CERTIFICATES
 
    At the Effective Time, (i) all shares of ISCG Common Stock outstanding
immediately prior to the Effective Time will automatically be canceled and
retired and will cease to exist, and all holders of certificates representing
shares of ISCG Common Stock that were outstanding immediately prior to the
Effective Time will cease to have any rights as shareholders of ISCG, and (ii)
the stock transfer books of ISCG will be closed with respect to all shares of
ISCG Common Stock outstanding immediately prior to the Effective Time. No
further transfer of any such shares of ISCG Common Stock will be made on such
 
                                       63
<PAGE>
stock transfer books after the Effective Time. If, after the Effective Time, an
ISCG Stock Certificate is presented to the Exchange Agent (or to ISCG or FCG),
such ISCG Stock Certificate will be canceled and will be exchanged as provided
above under the caption "--Conversion of Shares; Procedure for Exchange of
Certificates" and "--Merger Consideration."
 
CORPORATE MATTERS
 
    As of the Effective Time, the Articles of Incorporation of the Surviving
Corporation will be amended and restated to conform to the Certificate of
Incorporation of Merger Sub as in effect immediately prior to the Effective Time
with the exception that the name of the Surviving Corporation shall be

Corporation will be amended and restated to conform to the Bylaws of the Merger

warranty made by ISCG in the Reorganization Agreement; (ii) any event,
condition, fact or circumstance that occurs, arises or exists after the date of
the Reorganization Agreement and that would cause or constitute a material
inaccuracy in any representation or warranty made by ISCG in the Reorganization
Agreement if (A) such representation or warranty had been made as of the time of
the occurrence, existence or discovery of such event, condition, fact or
circumstance, or (B) such event, condition, fact or circumstance had occurred,
arisen or existed on or prior to the date of the Reorganization Agreement; (iii)
any event, condition, fact or circumstance hereafter arising which, if existing
or occurring at the date of the Reorganization Agreement, would have been
required to be set forth or described in the disclosure schedule that has been
prepared by ISCG in accordance with the requirements of Section 9.6 of the
Reorganization Agreement and that has been delivered by ISCG to FCG on the date
of the Reorganization Agreement (the "ISCG Disclosure Schedule"); (iv) any
material breach of any covenant or obligation of ISCG; and (v) any event,
condition, fact or circumstance that would make the timely satisfaction of any

                                       69
<PAGE>
    If any event, condition, fact or circumstance that is required to be
disclosed by ISCG to FCG requires any change in the ISCG Disclosure Schedule, or
if any such event, condition, fact or circumstance would require such a change
assuming the ISCG Disclosure Schedule were dated as of the date of the
occurrence, existence or discovery of such event, condition, fact or
circumstance, then ISCG shall promptly deliver to FCG an update to the ISCG
Disclosure Schedule specifying such change. No such update shall be deemed to
supplement or amend ISCG Disclosure Schedule for the purpose of (i) determining
the accuracy of any of the representations and warranties made by ISCG in the
Reorganization Agreement, or (ii) determining whether any of the conditions to
FCG and Merger Sub's obligation to close has been satisfied.
 
    NON-SOLICITATION.  Pursuant to the Reorganization Agreement, ISCG has agreed
that it will not, directly or indirectly, and will not authorize or permit any
of the other Acquired Corporations or any representative of the Acquired
Corporations to, (i) solicit, initiate, encourage or induce the making,
submission or announcement of any Acquisition Proposal or take any action that
could be reasonably expected to lead to an Acquisition Proposal, (ii) furnish
any information regarding any of the Acquired Corporations to any person in
connection with or in response to an Acquisition Proposal, (iii) engage in
discussions with any person with respect to any Acquisition Proposal, (iv)
approve, endorse or recommend any Acquisition Proposal or (v) enter into any
letter of intent or similar document or any contract contemplating or otherwise
relating to any Acquisition Transaction. ISCG is not prevented, however, from
furnishing nonpublic information regarding the Acquired Corporations to, or
entering into discussions with, any person in response to a Superior Offer or
engaging in discussions with respect thereto if (i) neither ISCG nor any
representative of the Acquired Corporations shall has violated any of its
obligations against non-solicitation, (ii) the ISCG Board of Directors
determines in good faith, based upon the advice of its outside counsel, that
such action is required in order for the ISCG Board of Directors to comply with
its fiduciary duties under applicable law, (iii) prior to furnishing any
nonpublic information to, or entering discussions with any person, ISCG gives
FCG written notice of the identity of such person and of ISCG's intention to
furnish nonpublic information to, or enter into discussions with, such person,
and ISCG receives from such person an executed confidentiality agreement
containing customary limitations on the use and disclosure of all nonpublic
written and oral information furnished to such person by ISCG, and (iv) prior to
furnishing any such nonpublic information to, or entering into discussions with,
such person, ISCG furnishes such nonpublic information to FCG (to the extent
such nonpublic information has not been previously furnished by ISCG to FCG). In
addition to the foregoing, ISCG shall (A) provide FCG with at least 24 hours
prior notice of any meeting of ISCG's Board of Directors at which ISCG's Board
of Directors is reasonably expected to consider a Superior Offer and (B) not
recommend a Superior Offer to its shareholders for a period of not less than the
greater of two business days or 48 hours after FCG's
receipt of a copy of such Superior Offer.
 
   
    An "Acquisition Proposal" is any offer or proposal contemplating or
otherwise relating to any "Acquisition Transaction." An "Acquisition
Transaction" is any transaction or series of related transactions involving: (i)
any merger, consolidation, share exchange, business combination, issuance of
securities, acquisition of securities, tender offer, exchange offer or other
similar transaction (A) in which any of the Acquired Corporations is a
constituent corporation, (B) in which any person or "group" (as defined in the
Securities and Exchange Act of 1934, as amended (the "Exchange Act") and the
rules thereunder) of persons directly or indirectly acquires ISCG or more than
50% of the Company's business or directly or indirectly acquires beneficial or
record ownership of securities representing more than 20% of the outstanding
securities of any class of voting securities of any of the Acquired Corporation,
or (C) in which any of the Acquired Corporations issues securities representing
more than 20% of the outstanding securities of any class of voting securities of
ISCG; (ii) any sale, lease, exchange, transfer, license, acquisition or
disposition of more than 50% of the assets of ISCG; or (iii) any liquidation or
dissolution of ISCG.
    
 
    A "Superior Offer" is an unsolicited, bona fide written offer made by a
third party to purchase more than 50% of the outstanding shares of ISCG Common
Stock on terms that the ISCG Board of Directors
 
                                       70
<PAGE>
determines, in its reasonable judgment, based upon the written advice of its
financial advisor, to be more favorable to ISCG's shareholders than the terms of
the Merger, except that no such offer shall be deemed to be a "Superior Offer"
if any financing required to consummate the transaction contemplated by such
offer is not committed and is not likely to be obtained by such third party on a
timely basis.
 
    MEETINGS OF SHAREHOLDERS AND STOCKHOLDERS.  Pursuant to the Reorganization
Agreement, ISCG will take all action necessary in accordance with applicable law
to convene and hold the ISCG Special Meeting to vote upon the approval of the
Reorganization Agreement and the Merger. ISCG's obligation to call, give notice
of, convene and hold the ISCG Special Meeting will not be limited or otherwise
affected by the commencement, disclosure announcement or submission to ISCG of
an Acquisition Proposal or by the withdrawal, amendment or modification of the
recommendation of the ISCG Board of Directors with respect to the Merger.
Pursuant to the Reorganization Agreement, FCG will take all action necessary to
call, give notice of, convene and hold the FCG Special Meeting to vote upon the
issuance of FCG Common Stock in the Merger.
 
    Neither the board of directors of ISCG or FCG nor any committee thereof is
permitted to withdraw, amend or modify, or propose or resolve to withdraw, amend
or modify, in a manner adverse to the other party, its recommendations in favor
of the Reorganization Agreement and the Merger in the case of ISCG, and the
issuance of FCG Common Stock in the case of FCG. However, notwithstanding the
foregoing, the ISCG Board of Directors will not be prevented from withdrawing,
amending or modifying its unanimous recommendation in favor of the Merger if (i)
a Superior Offer is made to ISCG and is not withdrawn, (ii) neither ISCG nor any
of its representatives has violated the covenants given by them concerning non-
solicitation and (iii) the ISCG Board of Directors concludes in good faith,
based upon the advice of its outside counsel, that, in light of such Superior
Offer, the withdrawal, amendment or modification of such recommendation is
required in order for the ISCG Board of Directors to comply with its fiduciary
obligations.

Securities Act) takes any action that could adversely affect the ability of FCG

        (ii) by either FCG or ISCG if the Merger shall not have been consummated
    by January 31, 1999 (unless the failure to consummate the Merger is
    substantially attributable to a failure to act on the part of the party
    seeking to terminate the Reorganization Agreement to perform any material
    obligation required to be performed by such party at or prior to the
    Effective Time);
 
       (iii) by either FCG or ISCG if a court of competent jurisdiction or other

    such action or failure to act constitutes a material breach by ISCG of the
    Reorganization Agreement);

    inaccurate, or if any of ISCG's covenants contained in the Reorganization
    Agreement shall have been breached in any material respect; provided,
    however, that if an inaccuracy in ISCG's representations and warranties or a
    breach of a covenant by ISCG is curable by ISCG and ISCG is continuing to
    exercise all reasonable efforts to cure
 
                                       72

    basis on account of such inaccuracy or breach; or
 
      (viii) by ISCG if any of FCG's representations and warranties contained in
    the Reorganization Agreement shall be or shall have become materially
    inaccurate, or if any of FCG's covenants contained in the Reorganization
    Agreement shall have been breached in any material respect; provided,
    however, that if an inaccuracy in FCG's representations and warranties or a
    breach of a covenant by FCG is curable by FCG and FCG is continuing to
    exercise all reasonable efforts to cure such inaccuracy or breach, then ISCG
    may not terminate the Reorganization Agreement on this basis on account of
    such inaccuracy or breach.
 
    A "Triggering Event" shall be deemed to have occurred if: (i) the ISCG Board

                          INFORMATION RELATING TO FCG
 
FCG BUSINESS
 
OVERVIEW
 
    FCG provides operations improvement and information management services to
payors, providers, government agencies and other healthcare organizations in
North America and Europe. FCG's services are designed to increase its clients'
operations effectiveness in order to reduce cost, improve customer service and
enhance the quality of patient care. Operations effectiveness offers a means to
improve the financial, administrative and clinical processes within a client
organization. FCG's services address the increasing need for healthcare-specific
information technology expertise to objectively evaluate, select, implement and
manage an optimal set of information systems, networks and applications. FCG has
over 560 consultants who possess extensive expertise in key healthcare
financial, administrative and clinical processes, information technologies and
applications. FCG provides this expertise to clients by assembling
multi-disciplinary teams which provide comprehensive services across its four
principal services: consulting; software implementation; network and application
integration; and co-management services. FCG's services and consultants are
supported by internal research and a centralized information system which
provides real-time access to current industry and technology information and
project methodologies, experiences, models and tools. FCG believes that its
success is attributable to its strong relationships with industry leading
clients, the healthcare, technology and consulting expertise of FCG's
consultants, and the depth and breadth of its consulting services.
 
SERVICES
 
    FCG's four principal services consist of consulting, software
implementation, network and application integration and co-management services.
FCG typically is engaged on an assignment-by-assignment basis and assembles
client teams from one or more services to match the expertise and service
offerings with the overall objectives required by each client and engagement.
Many client engagements involve multiple assignments. FCG may assemble several
client teams to serve the needs of a single client. FCG provides its services at
the client site to senior-level management and other personnel within the client
organization.
 
    CONSULTING SERVICES
 
    FCG's consulting services primarily consist of strategic planning,
operations effectiveness, procurement and contracting, and general consulting.
 
    FCG's strategic planning services involve the development of strategic plans
for healthcare organizations encompassing one or more of the following areas:
the decision to purchase and implement large-scale clinical, patient information
or financial applications; the installation and integration of comprehensive
communications, network and other information technology systems; systems and
information architectures; and organizational and governance structures for
information technology departments. FCG believes that its strategic planning
services will continue to be the core of FCG's business as it provides a
foundation for the introduction of FCG's other services to clients and allows
FCG to develop multi-level relationships with its clients. FCG typically
provides its strategic planning services on a fixed-fee basis.
 
    The goal of each strategic plan is to enable the client to maximize the
value of its information technology investments and improve operations
effectiveness. To ensure that each plan addresses the strategic goals,
priorities and needs of the client, FCG's strategic planning process involves
the participation of several senior-level management personnel, clinicians,
physicians and other user groups within the client organization. FCG collects
information regarding the client's business strategies, information technology
applications and systems, the capabilities of the client's in-house technical
staff and the operational needs of user groups. FCG then identifies several
information and infrastructure needs which must be addressed in order to
implement the client's business strategies. FCG also develops a series of
 
                                       74
<PAGE>
prioritized recommendations or assignments to be completed by the client during
the next three to five years. These recommendations may include such items as
the installation of packaged software applications or communication networks, or
the use of clinical repositories or outcomes systems. The strategic plan
delivered to the client describes the recommendations in detail and typically
includes specific information technology alternatives, internal staffing
recommendations and implementation schedules and budgets. FCG also assists the
client in building consensus with respect to a particular strategic objective or
assignment.
 
    FCG's operations effectiveness services enhance its clients' performance
through financial, administrative and clinical process improvement. FCG believes
that information technology is the most important element in implementing a
successful business process redesign. Through its historic information
technology expertise and its emerging enterprise-level operations effectiveness
services, FCG provides the full set of skills required to address the increased
pressures facing its clients to reduce cost, improve customer service and
improve and measure quality of patient care. These services are closely
integrated with FCG's implementation and integration services to ensure that
clients receive maximum benefit from new systems installations.
 
    FCG provides information technology procurement and contracting services
that assist its clients with rapidly identifying, selecting and contracting for
the optimal information technology applications, networks and systems. FCG's
procurement and contracting consultants operate independently of hardware and
software vendors and accordingly provide objective assessments and
recommendations with respect to information technology alternatives and pricing.
Using these services, a client can efficiently identify and select an
appropriate vendor-based alternative, balance competing interests within the
client organization and, in many instances, negotiate price discounts and other
terms which may be difficult to achieve without FCG's involvement. FCG does not
purchase and resell hardware or software to its clients. FCG's procurement and
contracting services support FCG's strategic planning, implementation and
integration services by assisting clients in selecting and contracting with
vendors who will provide the applications, networks or systems to be installed
at the client site. FCG's procurement and contracting services are often
provided as part of a client's larger information technology, networking or
operational initiatives which may involve the provision of FCG's other services.
FCG typically provides its procurement and contracting services on a per-hour
basis.
 
    FCG's consultants typically assess the technical capabilities,
specifications and design philosophy of existing products and assist clients in
all stages of procurement such as system requirement assessment and definition,
procurement planning and management, requests for proposals, vendor evaluation
and selection and contract negotiation. FCG's procurement and contracting
services include such areas as clinical, patient, financial and managed care
systems, claims processing, outcomes systems, local area networks, wide area
networks, voice and video systems, electronic messaging, call centers, Internet
and web technologies and telemedicine.
 
    FCG also provides general information management consulting services to its
existing clients on an as-needed basis in connection with industry trends and
developments, product introductions or changing regulatory requirements. FCG's
general consulting services typically are provided directly to senior-level
client personnel and involve small-scale, short duration assignments that are
important in maintaining strong client relationships.
 
    SOFTWARE IMPLEMENTATION SERVICES
 
    FCG provides implementation services for packaged software products utilized
by healthcare organizations. These services include project management,
installation, interface programming, testing and training services. In providing
these services, FCG draws on proven methodologies and its extensive expertise in
healthcare processes and information technology to ensure that each
implementation is completed efficiently with minimal disruption to clients'
operations. FCG's implementation specialists
 
                                       75
<PAGE>
emphasize administrative and clinical process improvement and user training,
including technical support staff training, in each engagement. FCG typically
provides its implementation services on a fixed-fee per month or per-hour basis.
 
    Through its implementation services, FCG believes that it enables its
clients to maximize the value of each application investment. FCG typically
assembles a dedicated, on-site, multi-disciplinary team of consultants to
perform each implementation engagement. This team determines implementation
schedules and budgets with the client. FCG's implementation specialists may also
provide project management, quality assurance or an interface mapping and
programming function through which FCG efficiently installs the application and
ensures that, once installed, the application will communicate with other
applications and networks used by the client. This interface mapping and
programming function often requires that FCG develop a considerable amount of
additional software code. Training of client personnel involves all aspects of
the complete system. FCG has extensive expertise in implementing applications
from vendors such as Cerner Corporation, Erisco Systems, HBO & Company, IDX
Systems Corp., Medic Computer Systems, Inc., MedicaLogic, Inc., Meditech, Inc.,
PHAMIS Inc., PeopleSoft, Inc. and Shared Medical Systems Corporation. FCG
believes that its expertise with and independence from application vendors
provides clients with an objective, reliable resource to implement these
applications.
 
    NETWORK AND APPLICATION INTEGRATION SERVICES.
 
    FCG designs and develops comprehensive system architectures,
infrastructures, interfaces, databases, applications and networks to address the
need for information integration and dissemination throughout a healthcare
organization. FCG's network and application integration services emphasize
scalable architectures and systems that can accommodate an increasing array of
functions and features to address a client's emerging information needs. FCG
often identifies specific technology and service alternatives for each clinical
and operational site within the client organization in the course of each
integration plan and engagement. FCG's integration services typically involve
FCG's procurement and contracting and implementation services in order to assist
the client in acquiring the needed hardware and software and, in some cases, to
install the acquired software as part of the integration plan. FCG typically
provides its network and application integration services on a fixed fee,
per-hour, or fixed-fee per month basis as negotiated in individual client
contracts.
 
    FCG's network and application integration services are typically provided to
consolidated healthcare organizations, including integrated delivery networks
("IDNs") and health plans. Application integration assignments include the
development and implementation of master patient indices, computer-based patient
record systems, managed care and medical management systems, physician practice
management systems, clinical decision support and data repositories, and data
warehouses. Network integration assignments include the development of
information, technology and communication architectures and Internet, intranet
and desktop messaging systems. Network and application integration engagements
involve planning, designing and managing the installation and implementation of
hardware and software technologies. These engagements also involve comprehensive
site visits and user interviews, application programming and training across
multiple levels of a client organization. Often FCG prepares a detailed mapping
of physical, technical and operational elements of the integrated applications
or networks.
 
    CO-MANAGEMENT SERVICES
 
    FCG provides interim staffing for healthcare organizations primarily for
senior-level information technology positions such as Chief Information
Officers, Directors of Information Systems and information technology department
managers. FCG also provides information technology department outsourcing on a
temporary or permanent basis as determined by the client. FCG's co-management
services emphasize the importance of existing management and other information
technology personnel. Accordingly, FCG's personnel work with existing
information technology staff to address strategic business, information and
technology needs. FCG typically provides its co-management services on a
fixed-fee per month basis.

SERVICE DELIVERY
 
    FCG's services are provided by over 560 consultants who collectively have
expertise in key healthcare financial, administrative and clinical processes,
information technologies and applications. FCG believes that its healthcare
industry focus, information technology expertise, experienced consultants, and
research and practice support enable its clients to reduce cost, improve
customer service and enhance the quality of patient care.
 
    To ensure client satisfaction, FCG typically assigns a Client Service
Executive to each client team. The Client Service Executive's primary
responsibility is to establish and maintain long-term relationships with
clients. The Client Service Executive regularly communicates with the client to
ensure client satisfaction and is also responsible for billing decisions on each
assignment. For client engagements with multiple independent assignments, FCG
assigns a Delivery Service Executive to each assignment. A Delivery Service
Executive has specific technology, process or service line expertise and is
responsible for supervising the daily functions of the client team and for
ensuring that the team's progress is consistent with the client's objectives and
schedule. FCG measures every client's satisfaction through a client satisfaction
survey completed at six month intervals during the engagement and again at the
conclusion of each assignment.
 
    FCG employs consultants whose individual expertise combines healthcare,
information technology and consulting skills. FCG's consultants have developed
healthcare-specific expertise in key areas such as financial, administrative and
clinical processes, care management, clinical decision support, health plan
operations, medical and utilization management, outcomes and performance
management, physician practice management, ambulatory care and privacy and
confidentiality protection. FCG's consultants also have expertise in
implementing, integrating and developing a wide range of information technology
and management systems. These systems include packaged software applications,
client/server and object-oriented computing technologies, data repositories and
data warehousing, electronic commerce and electronic data imaging, networking,
web technologies, telemedicine, document management, security and disaster
recovery. FCG has expanded its recruiting efforts to ensure that it continues to
attract and retain the breadth and depth of skills and expertise necessary to
compete successfully in the healthcare consulting industry. FCG recruits and
retains its consultants by offering a combination of a growing healthcare
consulting practice, industry leading clients, intellectually challenging client
engagements and professional interaction and growth.
 
RESEARCH AND PRACTICE SUPPORT
 
    FCG's services and consultants are supported by internal research, training
and a centralized information system which provides real-time access to current
industry and technology information and project methodologies, experiences,
models and tools. FCG's principal research and practice support initiatives
include the Emerging Practices Group, Professional Development Programs,
Scottsdale Institute, KITE and Practice Guilds.
 
    EMERGING PRACTICES GROUP.  The Emerging Practices Group performs industry
research and collects, packages and distributes knowledge regarding emerging
trends in the healthcare industry. Examples of topics that the Emerging
Practices Group has researched are information management practices in emerging
IDNs, process design and redesign for cross continuum care management, impact of
government legislation, physician integration, Internet and intranet in
healthcare, and use of hand-held computing devices. FCG documents research
findings, conducts internal and client workshops on these topics, and makes the
research available for use in its client engagements.
 
    PROFESSIONAL DEVELOPMENT AND INCENTIVE PROGRAMS.  FCG has instituted several
professional development and incentive programs to encourage employee retention
and to provide support for the professional growth of all employees. FCG
provides training to its employees through an annual four-day educational
retreat, as well as ongoing classroom education, computer-based training,
distance learning and external
 
                                       77
<PAGE>
seminars. FCG has programs to educate all new employees about the history,
culture and practices of FCG. All employees are required to establish an annual
professional development plan for knowledge acquisition, skill development,
leadership assessment and training, project management and relationship
management. In addition to such programs, FCG encourages equity participation by
all employees. All vice presidents must purchase a multiple of their annual
salary in FCG Common Stock through the 1994 Restricted Stock Plan, as amended
(the "1994 Restricted Stock Plan"). See "Management--1994 Restricted Stock Plan
and Agreements." All other employees are eligible to participate in the
Associate 401(k) and Stock Ownership Plan (the "ASOP"), which matches 50% of
employee contributions with a contribution of FCG Common Stock by FCG. See
"Management- Associate 401(k) and Stock Ownership Plan."
 
    SCOTTSDALE INSTITUTE.  FCG's Scottsdale Institute is a membership
organization composed of more than 25 healthcare organizations across the United
States, typically represented by their Chief Executive Officers, Chief Operating
Officers or Chief Information Officers. Membership is by invitation only. The
Scottsdale Institute provides its members with a cost-sharing vehicle for
information exchange, problem-solving and learning related to improving
operations effectiveness through information management. The Emerging Practices
Group performs guided research projects in collaboration with groups of three to
five Scottsdale Institute member organizations that share common characteristics
and information management needs. The Emerging Practices Group delivers research
reports and tools to member organizations in areas such as management
techniques, organizational models, benchmarking and best practices,
methodologies, plans, and vendor information. This research enables FCG to
develop practical, applied solutions to problems of leading healthcare
organizations and to anticipate service needs of the broader market.
 
    KNOWLEDGE AND INFORMATION TECHNOLOGY EXCHANGE.  FCG's personnel have access
to FCG's internal research and to current industry and technology information
and project methodologies, experiences, models and tools through KITE. KITE
currently houses over 6,000 documents that include industry information, service
methodologies and tools, benchmarks and best practice information and other
documentation to support FCG's services and consultants. KITE is updated on a
continuous basis with information resulting from each engagement, by the
Emerging Practices Group, and by the Practice Guilds. FCG believes that this
resource allows its consultants to utilize engagement-specific information which
improves the quality and content of services delivered to clients while reducing
cost of delivery.
 
CLIENTS
 
    In 1997, FCG provided services to over 360 clients consisting of providers,
payors and other healthcare organizations in North America and Europe. During
the first six months of 1998, FCG provided services to over 320 clients. FCG's
clients include leading IDNs, health plans, acute care centers, academic medical
centers, physician organization, governmental agencies and other organizations.
 
SALES AND MARKETING
 
    FCG generates a substantial portion of its revenue from existing clients and
client referrals and markets its services primarily through its vice presidents.
FCG's vice presidents develop strong relationships with senior-level information
management and other decision-making personnel at leading healthcare
organizations, and are therefore positioned to market additional strategic and
information technology consulting services to FCG's existing clients. FCG
maintains these relationships by successfully completing assignments and meeting
clients' expectations. In particular, FCG believes that by successfully
completing strategic plans for new and existing clients, its vice presidents
will have significant opportunities to offer implementation and integration
services to these clients. FCG has demonstrated that this strategy leads to
expanded opportunities with its clients and referrals to new clients. In
providing its services, FCG attains an in-depth understanding of its client's
processes and internal information technology and business strategies. Through
this understanding, FCG plans to provide operations effectiveness services to a
greater portion of its client base. Operations effectiveness services involve
assessing, designing and improving
 
                                       78
<PAGE>
financial, administrative and clinical process. FCG's vice presidents and
practice directors allocate a significant portion of their time to business
development and related activities. FCG also employs six specialists who are
responsible for new business development with targeted clients.
 
    FCG is frequently engaged to provide multiple services throughout several
phases of a client's information technology system lifecycle, including
planning, procurement and contracting, implementation, integration and
management. As a result of this involvement, FCG's personnel often develop an
in-depth understanding of the client's systems and capabilities and develop
strong relationships with personnel within the client organization. These
relationships provide FCG with significant opportunities to undertake additional
assignments for each client.
 
    In addition to generating assignments from existing clients, FCG attracts
new clients through its targeted marketing activities. FCG's marketing
activities include public speaking, publishing press releases and trade show
participation. FCG also maintains research reports and "white papers" on its web
site, along with other company and industry information. FCG's marketing staff
produces a number of sales support tools including presentations, brochures,
article reprints, descriptions of FCG's services and case studies.
 
INTERNATIONAL OPERATIONS
 
    FCG has provided its consulting, implementation and integration services to
clients in Canada, Germany, France, Spain, Ireland, Mexico and the United
Kingdom, and maintains offices in Dublin, Ireland and London, Macclesfield and
Belfast, United Kingdom. On January 13, 1998, FCG completed the acquisition of a
small healthcare consulting firm in the United Kingdom, Greenhalgh and Company
Limited. On June 1, 1998, FCG completed the acquisition of all the assets and
hired all the employees of an application development firm, the Windrose Group,
based in Honduras. FCG believes that select international acquisitions will
enhance its ability to effectively serve clients in targeted international
markets.
 
    FCG intends to expand its international consulting services, which will
require a significant amount of management's attention and FCG's human and
financial resources. FCG may establish additional international operations and
hire additional personnel. There can be no assurance that FCG will be able to
successfully recruit and retain the necessary number of highly skilled
consultants in each country in which it intends to conduct its operations. Any
inability to recruit and retain such employees could impair FCG's ability to
expand internationally and may have a material adverse effect on FCG's business,
financial condition and results of operations. In addition, there can be no
assurance that FCG will be able to establish international market demand for its
services. FCG's international business may be subject to a variety of risks,
including the difficulty of tailoring its services to individual countries'
healthcare market needs, currency fluctuations, potentially longer payment
cycles, potential difficulties in collecting international accounts receivable,
the enforcement of contractual obligations and intellectual property rights,
potentially adverse tax consequences, increased costs associated with
maintaining international marketing efforts, costs of localizing services in
international markets, adverse changes in regulatory requirements and possible
economic downturns outside of the United States. There can be no assurance that
such factors will not have a material adverse effect on FCG's future
international operations and, consequently, on its business, financial condition
and results of operations.

EMPLOYEES
 
    As of June 30, 1998, FCG had 707 employees, 53 of whom were vice presidents.
FCG's vice presidents are stockholders of FCG and are responsible for new
business development, client relationships, company leadership, service delivery
and the long-term strategy of FCG. FCG believes that its relationship with its
employees is good.

space in the Long Beach headquarters to accommodate future growth.
 
LEGAL PROCEEDINGS
 
    From time to time, FCG may be involved in claims or litigation that arise in
the normal course of business. As of the date of this Prospectus, FCG is not a
party to any legal proceedings which, if decided adversely to FCG, would have a
material adverse effect on FCG's business, financial condition or results of
operations.

Joint Proxy Statement/Prospectus contains certain forward-looking statements
that involve risks and uncertainties, such as statements of FCG's plans,
objectives, expectations and intentions. The cautionary statements made in this
Joint Proxy Statement/Prospectus should be read as being applicable to all
related forward-looking statements wherever they appear in this prospectus.
FCG's actual results could differ materially from those discussed here. Factors

this section and the sections entitled "Risk Factors" and "FCG Business" as well
as those discussed elsewhere in this Joint Proxy Statement/Prospectus.
 
OVERVIEW
 
    FCG provides information technology and other consulting services to payors,
providers and other healthcare organizations in North America and Europe. FCG's
services are designed to increase its clients' operations effectiveness in order
to reduce cost, improve customer service and enhance the quality of patient
care. FCG's services address the increasing need of its clients for
healthcare-specific information technology expertise to objectively evaluate,
select, implement and manage an optimal set of information systems and
infrastructures. FCG's consultants provide this expertise through
multi-disciplinary teams specifically formed to provide a unique solution for
each client. FCG believes that its success is attributable to its strong
relationships with industry-leading clients, the healthcare, technology and
consulting expertise of FCG's consultants, and the depth and breadth of its
consulting services.
 
    FCG generates substantially all of its revenue from fees for professional
services. FCG typically bills for its services on an hourly, fixed-fee or
monthly fixed-fee basis as specified by the agreement with a particular client.
FCG establishes standard hourly rates for each level of consultant based on
several factors including industry and assignment-related experience, technical
expertise, skills and knowledge. For services billed on an hourly basis, fees
are determined by multiplying the amount of time expended on each assignment by
the hourly rate for the consultant(s) assigned to the engagement. Fixed fees are
established on a per-assignment or monthly basis and are based on several
factors such as the size, scope, complexity and duration of an assignment and
the number of consultants required to complete the assignment. Actual hourly or
fixed fees for an assignment may vary from the standard or historical rates
charged by FCG. For services billed on an hourly basis, FCG recognizes revenue
as services are performed. For services billed on a fixed fee basis, FCG
recognizes revenue using the percentage of completion method based on the amount
of time completed on each assignment versus the projected number of hours
required to complete such assignment. Revenue is recorded as incurred at
assignment rates net of unplanned adjustments for specific engagements.
Unplanned adjustments to revenue are booked at the time they are known. FCG may
obtain payment in advance of providing services. These advances are recorded as
deferred revenue and reflected as a liability on FCG's balance sheet.
 
    Cost of services primarily consists of the salaries, bonuses and related
benefits of consultants, subcontractor expenses, and the costs of FCG's
supplemental executive retirement plan. General and administrative expenses
primarily consist of the costs attributable to: office space occupancy;
investments in FCG's information systems, research and practice support and
quality initiatives; salaries and expenses for executive management, financial
accounting and administrative personnel; recruiting fees and professional
development; and marketing, legal and other professional services.
 
    In connection with the ASOP and certain non-qualified stock options granted
to FCG's vice presidents, FCG recognizes a compensation expense on its
consolidated statement of operations. The recurring portion of FCG's
compensation expense relating to stock issuances and the amortization of
deferred
 
                                       81
<PAGE>
compensation is reflected in FCG's consolidated statements of operations as
general and administrative expenses or cost of services based on the function of
the employee to whom the charge relates. FCG currently grants all stock options
at fair market value. In connection with the ASOP, FCG matches employee 401(k)
contributions with shares of FCG Common Stock based on the fair market value of
the shares at the time matching contributions are made.
 
    FCG's most significant expenses are its human resource and related salary
and benefit expenses. As of June 30, 1998, approximately 79% of FCG's 707
employees were consultants, and the salaries and benefits of such consultants
are recognized in FCG's cost of services. Non-billable employee salaries and
benefits are recognized as a component of general and administrative expenses.
FCG's cost of services as a percentage of revenue is directly related to its
consultant utilization, which is the ratio of total billable hours to available
hours in a given month. FCG manages consultant utilization by monitoring
assignment requirements and timetables, available and required skills, and
available consultant hours per week and per month. The number of consultants
staffed on an assignment will vary according to the size, complexity, duration
and demands of the assignment. Assignment terminations, completions and
scheduling delays may result in periods in which consultants are not optimally
utilized. An unanticipated termination of a significant assignment or an overall
lengthening of the sales cycle could result in a higher than expected number of
unassigned consultants and could cause FCG to experience lower margins. In
addition, the opening of new offices, expansion into new markets, and the hiring
of consultants in advance of client assignments have resulted and may continue
to result in periods of lower consultant utilization. During the second and
third quarters of 1996, FCG experienced a significant decrease in the
utilization of billable personnel. This decrease in utilization was primarily
attributable to the increased hiring of consultants and a failure by FCG to
assign underutilized consultants located in the central United States to
projects outside such region. FCG believes that this failure to re-assign
underutilized consultants was attributable to certain incentive programs which
have since been discontinued. This decrease in utilization, as well as certain
infrastructure upgrades, resulted in a decrease in net income in the second and
third quarters of 1996. There can be no assurance that such a decrease in
utilization or net income will not occur in the future.
 
    FCG's effective tax rate has varied from period to period due to differences
between book and tax deductions associated with certain non-deductible operating
expenses, including certain compensation expenses related to the ASOP.
 
COMPARISON OF SIX MONTHS ENDED JUNE 30, 1998 AND 1997
 
    NET REVENUE.  FCG's net revenue increased to $60.4 million, or 44.4%, for
the six months ended June 30, 1998 from $41.8 million for the six months ended
June 30, 1997. This increase was primarily attributable to an increase in
revenue from FCG's implementation, operations effectiveness, and integration
services.
 
    COST OF SERVICES.  Cost of services increased to $33.4 million, or 35.0%,
for the six months ended June 30, 1998 from $24.7 million for the six months
ended June 30, 1997. The increase was primarily attributable to an increase in
the number of consultants. Cost of services as a percentage of revenue decreased
to 55.3% for the six months ended June 30, 1998 from 59.1% for the six months
ended June 30, 1997. This decrease was primarily attributable to increased
realization of standard fees and a higher proportion of billable associates to
total associates during the quarter ended June 30, 1998.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $20.7 million, or 46.5%, for the six months ended June 30, 1998
from $14.2 million for the six months ended June 30, 1997. General and
administrative expenses as a percentage of revenue increased to 34.3% for the
six months ended June 30, 1998 from 33.8% for the six months ended June 30,
1997. This increase was primarily attributable to an increase in FCG's hiring,
including increased hiring from its expansion into Europe.
 
                                       82
<PAGE>
    COMPENSATION EXPENSES RELATED TO STOCK ISSUANCES.  Compensation expenses
related to stock issuances decreased to zero for the six months ended June 30,
1998 from $1.0 million for the six months ended June 30, 1997. This decrease was
attributable to the discontinuance of certain compensatory stock and option
issuances.
 
    INTEREST INCOME, NET.  Interest income, net of interest expense, increased
to $797,000 for the six months ended June 30, 1998 from $48,000 net expense for
the six months ended June 30, 1997. Interest income net of interest expense as a
percentage of revenue increased to 1.3% for the six months ended June 30, 1998
from (0.1%) for the six months ended June 30, 1997. This increase was primarily
attributable to the investment of net proceeds from FCG's initial public
offering in February 1998.
 
    INCOME TAXES.  Income taxes as a percentage of income before income taxes
decreased to 47.8% for the six months ended June 30, 1998 from 55.4% for the six
months ended June 30, 1997 due to a reduction in certain non-deductible
compensation related expenses partly offset by the existence of non-deductible
foreign losses in the current period. The provision of 47.8% for the six months
ended June 30, 1998 represents the new estimated tax rate for the 1998 fiscal
year. This increased estimated rate is due to an expectation of losses in FCG's
foreign operations which are not currently deductible in any jurisdiction.
 
COMPARISON OF THE YEARS ENDED DECEMBER 31, 1997 AND 1996
 
    NET REVENUE.  FCG's net revenue increased to $91.6 million, or 39.1%, for
the year ended December 31, 1997 from $65.8 million for the year ended December
31, 1996. This increase was primarily attributable to an increase in revenue
from FCG's implementation and integration services and an increase in consultant
utilization.
 
    COST OF SERVICES.  Cost of services increased to $53.5 million, or 31.5%,
for the year ended December 31, 1997 from $40.7 million for the year ended
December 31, 1996. The increase was primarily attributable to an increase in the
number of consultants. Cost of services as a percentage of revenue decreased to
58.5% for the year ended December 31, 1997 from 61.9% for the year ended
December 31, 1996. This decrease was primarily attributable to increased
utilization rates for FCG's consultants during the year ended December 31, 1997.
FCG believes that the increase in utilization rates was primarily attributable
to the discontinuation of certain incentive programs and the resulting
reallocation of billable resources to projects across geographic regions.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $31.7 million, or 33.8%, for the year ended December 31, 1997 from
$23.7 million for the year ended December 31, 1996. This increase was primarily
attributable to FCG's relocation to a larger corporate facility, expanded
marketing initiatives, expansion into the United Kingdom, and continued efforts
to enhance and improve FCG's internal infrastructure including upgrades to its
management information systems. General and administrative expenses as a
percentage of revenue decreased to 34.6% for the year ended December 31, 1997
from 36.0% for the year ended December 31, 1996.
 
    COMPENSATION EXPENSES RELATED TO STOCK ISSUANCES.  Compensation expenses
related to stock issuances increased to $6.1 million for the year ended December
31, 1997 from $588,000 for the year ended December 31, 1996. This increase was
primarily attributable to a $4.2 million non-cash charge associated with an
allocation of 568,000 shares of FCG Common Stock to employees pursuant to a
one-time modification of the ASOP and a non-recurring compensation expense of
$1.2 million resulting from the difference between estimated average fair market
value and cost of the allocated ASOP shares.
 
COMPARISON OF YEARS ENDED DECEMBER 31, 1996 AND 1995
 
    NET REVENUE.  FCG's net revenue increased to $65.8 million, or 37.9%, for
the year ended December 31, 1996 from $47.7 million for the year ended December
31, 1995. This increase was primarily
 
                                       83
<PAGE>
attributable to an increase in revenue from implementation and integration
services and the expansion of such services to IDNs and health plans.
 
    COST OF SERVICES.  Cost of services increased to $40.7 million, or 53.5%,
for the year ended December 31, 1996 from $26.5 million for the year ended
December 31, 1995. This increase was primarily attributable to an increase in
the number of consultants. Cost of services as a percentage of revenue increased
to 61.9% for the year ended December 31, 1996 from 55.5% for the year ended
December 31, 1995. This increase was primarily attributable to a significant
decrease in utilization rates for consultants located in the central United
States. FCG believes that this decrease in utilization was attributable to
certain incentive programs which have since been discontinued.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $23.7 million, or 35.1%, for the year ended December 31, 1996 from
$17.5 million for the year ended December 31, 1995. This increase was primarily
attributable to an increase in the number of non-billable employees and expenses
relating to the improvement of FCG's infrastructure. General and administrative
expenses as a percentage of revenue decreased to 36.0% for the year ended
December 31, 1996 from 36.7% for the year ended December 31, 1995.
 
    COMPENSATION EXPENSES RELATED TO STOCK ISSUANCES.  Compensation expense
related to stock issuances increased to $588,000, or 52.7%, for the year ended
December 31, 1996 from $385,000 for the year ended December 31, 1995. This
increase was primarily attributable to stock options granted below fair market
value in 1996.
 
COMPARISON OF YEARS ENDED DECEMBER 31, 1995 AND 1994
 
    NET REVENUE.  FCG's net revenue increased to $47.7 million, or 58.9%, for
the year ended December 31, 1995 from $30.0 million for the year ended December
31, 1994. This increase was primarily attributable to an increase in the number
of new assignments and consultants and an increase in FCG's focus on working
with IDNs and health plans.
 
    COST OF SERVICES.  Cost of services increased to $26.5 million, or 57.2%,
for the year ended December 31, 1995 from $16.9 million for the year ended
December 31, 1994. The increase was primarily attributable to an increase in the
number of consultants. Cost of services as a percentage of revenue remained
relatively constant at 55.5% for the year ended December 31, 1995 from 56.1% for
the year ended December 31, 1994.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
increased to $17.5 million, or 77.5%, for the year ended December 31, 1995 from
$9.9 million for the year ended December 31, 1994. This increase was primarily
attributable to an increase in the number of non-billable employees, increased
recruiting and training expenses, continued geographical expansion and
investments in internal information technology systems. General and
administrative expenses as a percentage of revenue increased to 36.7% for the
year ended December 31, 1995 from 32.8% for the year ended December 31, 1994.
 
    COMPENSATION EXPENSES RELATED TO STOCK ISSUANCES.  Compensation expenses
related to stock issuances was $385,000 for the year ended December 31, 1995.
There was no corresponding expense in the prior period. This expense was
primarily attributable to stock options granted below fair market value in 1995.

    During the six months ended June 30, 1998, FCG generated cash flow from
operations of $5.8 million. During the six months ended June 30, 1998, FCG used
cash flow of approximately $2.2 million to purchase property and equipment,
including computer and related equipment and office furniture. Depreciation and
amortization expense for the six months ended June 30, 1998 was approximately
$1.4 million. During
 
                                       84
<PAGE>
the six months ended June 30, 1998, FCG generated cash flow of $43.8 million
from financing activities. At June 30, 1998, FCG had working capital of $30.6
million and long term investments of $25.7 million. At December 31, 1997, FCG
had working capital of $9.3 million. The primary reason for the increase was the
completion of FCG's initial public offering in February 1998.
 
    FCG has a revolving line of credit which allows FCG to borrow up to $6.0
million at an interest rate of the prevailing prime rate. The revolving line of
credit expires on December 31, 1998. There was no outstanding balance under the
line of credit at June 30, 1998. FCG has two term loan facilities ("Term Loan A"
and "Term Loan B"). Term Loan A is a $305,000 facility under which approximately
$257,000 was outstanding as of June 30, 1998. Term Loan A expires on July 1,
2003. Term Loan B is a $4.0 million facility under which approximately $440,000
was outstanding as of June 30, 1998. Term Loan B expires on December 4, 2001.
Term Loan A and Term Loan B bear interest at a rate per annum equal to the
prevailing prime rate plus 0.5%. All borrowings under FCG's credit facilities
are secured by FCG's accounts receivable and other rights to payment, general
intangibles and equipment. The line of credit agreement provides that FCG must
satisfy certain covenants and restrictions.

Chief Executive Officer of FCG, and Steven Heck was appointed President and
Chief of the Professional Practice. In addition, FCG announced that its

executives. Such appointments were made upon news that James A. Reep is in
serious condition after being diagnosed on September 30, 1998, with cancer. Mr.
Reep will continue to serve as Chairman of the Board and an employee of the
Company.
    
 
                                       88
<PAGE>
BOARD COMPOSITION
 
   
    FCG currently has authorized eight directors. In accordance with the terms
of the amended and restated certificate of incorporation, as amended, of FCG
(the "FCG Certificate of Incorporation"), the terms of office of the FCG Board
of Directors will be divided into three classes: Class I, whose term will expire
at the annual meeting of stockholders to be held in 1999; Class II, whose term
will expire at the annual meeting of stockholders to be held in 2000; and Class
III, whose term will expire at the annual meeting of stockholders to be held in
2001. The Class I directors are Stephen Olson and Steven Heck, the Class II
directors are Stanley R. Nelson, Luther J. Nussbaum and Jack O. Vance and the
Class III directors are Scott S. Parker, Steven Lazarus and James A. Reep. At
each annual meeting of stockholders after the initial classification, the
successors to directors whose term will then expire will be elected to serve
from the time of election and qualification until the third annual meeting
following election. In addition, the FCG Certificate of Incorporation provides
that the authorized number of directors may be changed only by resolution of the
FCG Board of Directors. Any additional directorships resulting from an increase
in the number of directors will be distributed among the three classes so that,
as nearly as possible, each class will consist of one-third of the directors.
This classification of the FCG Board of Directors may have the effect of
delaying or preventing changes in control or management of FCG. Although
directors of FCG may be removed for cause by the affirmative vote of the holders
of a majority of the FCG Common Stock, the FCG Certificate of Incorporation
provides that holders of two-thirds of the FCG Common Stock must vote to approve
the removal of a director without cause.
    
 
    Under the terms of the Reorganization Agreement, as soon as practicable
after the Effective Time, FCG has agreed to use reasonable efforts to nominate
and appoint (i) Warren V. Musser, or such other nominee designated by ISCG, to
Class I of the FCG Board to serve until the annual meeting of stockholders to be
held in 1999, and (ii) David S. Lipson, or such other nominee designated by
ISCG, to Class II of the FCG Board to serve until the annual meeting of
stockholders to be held in 2000.
 
BOARD COMMITTEES
 
    The Audit Committee of the FCG Board of Directors reviews the internal
accounting procedures of FCG and consults with, and reviews the services
provided by, FCG's independent auditors. The Compensation Committee of the FCG
Board of Directors reviews and recommends to the FCG Board of Directors the
compensation and benefits of all officers of FCG and reviews general policy
relating to compensation and benefits of employees of FCG. The Compensation
Committee also administers the issuance of stock options and other awards under
FCG's stock plans.
 
DIRECTOR COMPENSATION
 
    FCG currently provides annual cash compensation in the amount of $10,000 to
directors for services in such capacity. Directors are also reimbursed for
certain expenses in connection with attendance at Board of Directors and
committee meetings. Directors receive automatic grants of nonstatutory stock
options under the 1997 Non-Employee Directors' Stock Option Plan and are
eligible for grants of nonstatutory stock options under the 1997 Equity
Incentive Plan. Currently, each non-employee director is required to purchase
and hold shares with an aggregate fair market value equal to the annual fees
paid to the directors under the Non-Employee Director Restricted Stock Plan.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
   
    The bylaws of FCG (the "FCG Bylaws") provide that FCG will indemnify its
directors and executive officers and may indemnify its other officers, employees
and other agents to the fullest extent permitted by Delaware law. FCG is also
empowered under the FCG Bylaws to enter into indemnification contracts with its
directors and officers and to purchase insurance on behalf of any person it is
required or permitted to indemnify. Pursuant to this provision, FCG expects to
enter into indemnification agreements with each of its directors and executive
officers.
    
 
    FCG has obtained officer and director liability insurance with respect to
liabilities arising out of certain matters, including matters arising under the
Securities Act. In addition, the FCG Certificate of Incorporation provides that,
to the fullest extent permitted by Delaware law, FCG's directors will not be
liable for monetary damages for breach of the directors' fiduciary duty of care
to FCG and its stockholders. This provision in the FCG Certificate of
Incorporation does not eliminate the duty of care, and in appropriate
circumstances, equitable remedies such as an injunction or other forms of
non-monetary relief would remain available under Delaware law. Under current
Delaware law, a director's liability to FCG or its stockholders may not be
limited with respect to any breach of the director's duty of loyalty to FCG or
its stockholders, for acts or omissions not in good faith or involving
intentional misconduct, for knowing violations of law, for any transaction from
which the director derived an improper personal benefit, for improper

CERTAIN TRANSACTIONS OF FCG
 
    FCG and its vice presidents have entered into certain agreements relating to
the issuance of FCG's securities. Under the provisions of the 1994 Restricted
Stock Plan, FCG's vice presidents have entered into Restricted Stock Agreements
("RSAs") that require each vice president to purchase a minimum number of shares
of FCG Common Stock. Shares of FCG Common Stock are purchased under the RSAs at
a price per share equal to the price as quoted on Nasdaq. On and prior to July
30, 1997, FCG also provided certain of its vice presidents with non-qualified
stock options to purchase shares of FCG Common Stock based on the number of
shares purchased under the RSAs. These options were granted with exercise prices
below the then-prevailing market value for shares of FCG Common Stock as
determined by an independent valuation firm. In connection with the RSAs and
stock option agreements entered into between FCG and its vice presidents FCG
has, from time to time, made certain loans to its vice presidents equal to the
following: (i) the aggregate purchase price for shares of FCG Common Stock
purchased by a vice president under the 1994 Restricted Stock Plan; (ii) the
aggregate exercise price for stock options exercised by a vice president in
connection with the 1994 Restricted Stock Plan; and (iii) the aggregate amount
of medicare and income taxes payable by a vice president as a result of the
exercise of stock options granted in connection with the 1994 Restricted Stock
Plan. The promissory notes evidencing such loans are generally non-recourse,
non-interest bearing, and have a stated term of ten years. FCG records a
compensation expense and FCG's vice presidents recognize income on the imputed
interest attributable to these notes. Shares of FCG Common Stock purchased under
the RSAs or pursuant to the exercise of stock options, for which purchase or
exercise a loan was granted, are pledged as security for the outstanding
principal amounts of the loans. Each vice president is required to pledge that
number of shares having a market value equal to 120% of the amount remaining due
under the loans. The RSAs require FCG's vice presidents to repay the outstanding
principal amounts of such loans at the greater of (i) one-tenth (1/10) of the
face amount of such loans, and (ii) one-half (1/2) of the vice presidents' net
after tax annual bonus. FCG's vice presidents may repay the outstanding
principal amounts in advance without penalty. As of December 31, 1997, all of
the outstanding options under these arrangements have been exercised and the
outstanding aggregate principal amount under these loans equaled approximately
$9.3 million. In the future, FCG plans to grant all stock options at market
value and to match employee 401(k) contributions with shares of FCG Common Stock
based on the market value of the shares at the time of grant.
 
   
    FCG has an ongoing, non-contractual business relationship with First Ticket
Travel, whose sole proprietor is Fatima Reep, the wife of James A. Reep,
Chairman of the Board, and former Chief Executive Officer and President of FCG.
For the year ended December 31, 1997, FCG has purchased travel services from
First Ticket Travel in the amount of approximately $124,000.
    
 
    FCG entered into a consulting agreement with Stanley R. Nelson on September
1, 1997. The agreement provides that Mr. Nelson will be paid up to a maximum of
$11,115 per month, for consulting services related to the administration of and
strategic planning for the Scottsdale Institute.
 
    FCG has entered into indemnification agreements with its directors and
officers for the indemnification of and advancement of expenses to such persons
to the full extent permitted by law. FCG also intends to execute such agreements
with its future directors and officers.
 
    FCG believes that the foregoing transactions were in its best interest. As a
matter of policy the transactions were, and all future transactions between FCG
and any of its officers, directors or principal stockholders will be, approved
by a majority of the independent and disinterested members of the FCG Board of
Directors, will be on terms no less favorable to FCG than could be obtained from
unaffiliated third parties and will be in connection with bona fide business
purposes of FCG.

     Commission and generally includes voting or investment power with respect
     to securities. Except as indicated by footnote, and subject to community
     property laws where applicable, FCG believes, based on information

     sole voting and investment power with respect to all shares of FCG Common

     the average interest rate compounded quarterly which FCG pays to a
     commercial lending institution in a calendar quarter (the "Growth Factor").
     In the event FCG has no borrowings for a particular quarter, then the
     Growth Factor shall be the prime rate on the first day of the quarter, as

     discontinues such announcements, then it shall be the prime rate as
     announced by Bank of America.

value (the "FCG Preferred Stock"). As of the Record Date, there were [         ]
shares of FCG Common Stock outstanding held of record by [      ] stockholders.
    
 
    FCG COMMON STOCK.  The holders of FCG Common Stock are entitled to one vote
for each share held of record on all matters submitted to a vote of the
stockholders. The holders of FCG Common Stock are entitled to receive ratably
such dividends as may be declared by the FCG Board of Directors out of funds
legally available therefor. In the event of a liquidation, dissolution or
winding up of FCG, holders of FCG Common Stock are entitled to share ratably in
all assets remaining after payment of liabilities. Holders of FCG Common Stock
have no preemptive rights and no right to convert their FCG Common Stock into
any other securities. There are no redemption or sinking fund provisions
applicable to the FCG Common Stock. All outstanding shares of FCG Common Stock
are, and all shares of FCG Common Stock to be outstanding after the completion
of the Merger will be, fully-paid and nonassessable.
 
    FCG PREFERRED STOCK.  The FCG Board of Directors has the authority, without
further action by the stockholders, to issue up to 10,000,000 shares of FCG
Preferred Stock, in one or more series and to fix the rights, preferences,
privileges and restrictions thereof, including dividend rights, conversion
rights, voting rights, terms of redemption, liquidation preferences, sinking
fund terms and the number of shares constituting any series or the designation
of such series, without any further vote or action by stockholders. The issuance
of FCG Preferred Stock could adversely affect the voting power of holders of FCG
Common Stock and the likelihood that such holders will receive dividend payments
and payments upon liquidation and could have the effect of delaying, deferring
or preventing a change in control of FCG. FCG has no present plan to issue any
shares of FCG Preferred Stock.
 
    DELAWARE GENERAL CORPORATION LAW AND CERTAIN CHARTER PROVISIONS.  FCG is
subject to the provisions of Section 203 of the DGCL, an anti-takeover law. In
general, the statute prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. For purposes of Section 203, a "business combination"
includes a merger, asset sale or other transaction resulting in a financial
benefit to the interested stockholder, and an "interested stockholder" is a
person who, together with affiliates and employees, owns (or within three years
prior, did own) 15% or more of the corporation's voting stock.
 
    The FCG Certificate of Incorporation and FCG Bylaws also require that, any
action required or permitted to be taken by stockholders of FCG must be effected
at a duly called annual or special meeting of the stockholders and may not be
effected by a consent in writing. In addition, special meetings of the
stockholders of FCG may be called only by the FCG Board of Directors, the
Chairman of the Board, the President of FCG, or by any person or persons holding
shares representing at least 10% of the outstanding capital stock of FCG. The
FCG Certificate of Incorporation also provides for a classified board and
specifies that the authorized number of directors may be changed only by
resolution of the FCG Board of Directors. These provisions may have the effect
of deterring hostile takeovers or delaying changes in control or management of
FCG. See "Management--Board Composition."
 
    REGISTRATION RIGHTS.  Pursuant to the Reorganization Agreement, FCG has
agreed to enter into the Registration Rights Agreement at Closing, which grants
the Holders certain rights with respect to the registration under the Securities
Act of shares of FCG Common Stock issued to the Holders in connection with the
Merger.

DESCRIPTION OF ISCG CAPITAL STOCK
 
   
    The authorized capital stock of ISCG consists of 25,000,000 shares of ISCG
Common Stock, par value $0.005 per share, and 500,000 shares of ISCG Preferred
Stock, par value $1.00 per share ("ISCG Preferred Stock"). As of the Record
Date, there were [      ] shares of ISCG Common Stock outstanding held of record
by [         ] shareholders and       shares of ISCG Preferred Stock outstanding
and held of record by       shareholders.
    
 
    ISCG COMMON STOCK.  The holders of ISCG Common Stock are entitled to one
vote for each share held of record on all matters submitted to a vote of
shareholders and do not have cumulative voting rights. Except as otherwise
required by law, all other matters are determined by a majority of the votes
cast. Holders of ISCG Common Stock are entitled to receive ratably such
dividends, if any, as may be declared by the ISCG Board of Directors out of
funds legally available therefor, subject to any preferential dividend rights of
outstanding ISCG Preferred Stock. Subject to the rights of holders of ISCG
Preferred Stock, upon the liquidation, dissolution or winding up of ISG, the
holders of ISCG Common Stock are entitled to receive ratably the net assets of
ISCG available after the payment of all debts and other liabilities. Holders of
the ISCG Common Stock have no preemptive, subscription, redemption or conversion
rights. The outstanding shares of ISCG Common Stock are fully paid and
nonasessable.
 
    ISCG PREFERRED STOCK.  ISCG, by resolution of the ISCG Board of Directors
and without any further vote or action by the shareholders, has the authority,
subject to certain limitations prescribed by law, to issue from time to time up
to an aggregate of 500,000 shares of ISCG Preferred Stock in one or more classes
or series and to determine the designation and the number of shares of any class
or series as well as the voting rights, preferences, limitations and special
rights, if any, of the shares of any such class or series, including the
dividend rights, dividend rates, conversion rights and terms, voting rights,
redemption rights and terms, and liquidation preferences. The issuance of ISCG
Preferred Stock may have the effect of delaying, deferring or preventing a
change of control of ISCG. As of the ISCG Record Date, there were no shares of
ISCG Preferred Stock outstanding, and ISCG has no plans to issue any shares of
ISCG Preferred Stock.
 
    PENNSYLVANIA BUSINESS CORPORATION LAW.  The PBCL expressly permits directors
of a corporation to consider the interests of constituencies other than
shareholders, such as employees, suppliers, customers and the community, in
discharging their duties. Further, the PBCL expressly provides that directors do
not violate their fiduciary duty solely by relying on shareholders' rights plans
or other antitakeover provisions of the PBCL.
 
    The effect of these provisions may be to deter hostile takeovers at a price
higher than the prevailing market price for the ISCG Common Stock. In some
circumstances, certain shareholders may consider these antitakeover provisions
to have a disadvantageous effect. Tender offers or other non-open market
acquisitions of shares are frequently made at prices above the prevailing market
price of a company's shares. In addition, acquisitions of shares by persons
attempting to acquire control through market purchases may cause the market
price of the ISCG Common Stock to reach levels that are higher than would
otherwise be the case. These antitakeover provisions may discourage any or all
of such acquisitions, particularly those of less than all of the ISCG Common
Stock, and may thereby prevent certain holders of ISCG Common Stock from having
an opportunity to sell their shares at a temporarily higher market price.
 
    PBCL contains four additional provisions that would have applied to ISCG had
the shareholders not opted out of these provisions. The shareholders of ISCG
amended the articles of incorporation on January 29, 1996 to opt out of the
"control transactions" provision, which provides for mandatory shareholder
notice of the acquisition of 20% of the voting power of a Pennsylvania
corporation and provides shareholders with the opportunity to demand "fair
value" for their shares upon acquisition of
 
                                       98
<PAGE>
voting power; the "business combination" provision, which limits a corporation
from engaging in any merger or business combination with an interested
shareholder unless certain conditions have been met; the "control share"
provision, which limits the voting power of the shareholders owning 20% or more
of a corporation's voting stock, and the "disgorgement" provision, which permits
a corporation to recover profits resulting from the sale of shares in certain
situations, including those where an individual or group attempts to acquire at
least 20% of the corporation's voting shares.
 
    TRANSFER AGENT AND REGISTRAR.  The transfer agent and registrar for the ISCG
Common Stock is Chase Mellon Shareholder Services, L.L.C.
 
                       COMPARISON OF SHAREHOLDERS' RIGHTS
 
    In connection with the Merger, the ISCG shareholders will be converting
their shares of ISCG Common Stock into shares of FCG Common Stock. FCG is a
Delaware corporation and ISCG is a Pennsylvania corporation, and the FCG
Certificate of Incorporation and the FCG Bylaws differ from the ISCG Articles of
Incorporation and the ISCG Bylaws in several significant respects. Because of
the differences between the DGCL and the PBCL, and the differences in the
charter documents of FCG and ISCG, the rights of a holder of FCG Common Stock
differ from the rights of a holder of ISCG Common Stock.
 
    Below is a summary of some of the important differences between the DGCL and
the PBCL and the charter documents of FCG and ISCG. It is not practical to
summarize all of such differences in this Joint Proxy Statement/Prospectus, but
some of the principal differences which could materially affect the rights of
ISCG shareholders include the following:
 
SIZE OF THE BOARD OF DIRECTORS
 
    In accordance with the DCGL, the FCG Certificate of Incorporation states
that the number of directors will be set exclusively by the FCG Board of
Directors and authorizes the FCG Board of Directors to change the number by
resolution. The number of directors of FCG is currently fixed at eight. The FCG
Board of Directors acting without stockholder approval may change such number.
 
    Under the PBCL, the number of directors is fixed by, or in the manner
provided in the bylaws or, if not so fixed, the number of directors is the same
as that stated in the articles of incorporation or three if no number is so
stated. The ISCG Bylaws fix the number of directors at eleven directors. The
PBCL vests the authority to amend the bylaws to change the number of directors
in the board of directors, subject to the power of the shareholders to change
such action.
 
CLASSIFIED BOARD OF DIRECTORS
 
    A classified board is one in which a certain number, but not all, of the
directors are elected on a rotating basis each year. The DGCL permits, but does
not require, a classified board of directors, pursuant to which the directors
can be divided into as many as three classes with staggered terms of office,
with only one class of directors standing for election each year. The FCG
Certificate of Incorporation provides for a classified board of directors with
three classes of directors.
 
    Under the PBCL, a corporation is permitted to adopt a classified board;
provided, however, that if the directors are classified, each class must be as
nearly equal in number as possible, the term of office of at least one class
must expire in each year and the members of a class must not be elected for a
period longer than four years. In contrast to the FCG Certificate of
Incorporation, the ISCG Articles of Incorporation do not provide for a
classified board.
 
CUMULATIVE VOTING
 
    In an election of directors under cumulative voting, each share of stock
normally having one vote is entitled to a number of votes equal to the number of
directors to be elected. A shareholder may then cast
 
                                       99
<PAGE>
all such votes for a single candidate or may allocate them among as many
candidates as the shareholder may choose. Under the DGCL, cumulative voting in
the election of directors is not available unless specifically provided in the
certificate of incorporation. The FCG Certificate of Incorporation does not
provide for cumulative voting.
 
    The PBCL provides that any shareholder is entitled to cumulate his votes in
the election of directors unless the articles of incorporation provide
otherwise. The ISCG Articles of Incorporation provide that the shareholders of
the corporation do not have any cumulative voting rights.
 
REMOVAL OF DIRECTORS
 
    Under the DGCL, if a corporation has a classified board, the stockholders
may remove a director only for cause, unless the certificate of incorporation
provides otherwise. The FCG Certificate of Incorporation and the FCG Bylaws
provide that any and all directors may be removed with cause by a vote of the
holders of a majority of shares entitled to vote at an election of directors,
and without cause by the vote of at least 66 2/3% of the shares entitled to vote
at an election of directors.
 
    Under the PBCL, any director or the entire board of directors of a
corporation may be removed, with or without cause, if the removal is approved by
the affirmative vote of a majority of the outstanding shares entitled to vote.
 
FILLING VACANCIES ON THE BOARD OF DIRECTORS
 
    Under the DCGL, vacancies and newly created directorships may be filled by a
majority of the directors then in office (even though less than a quorum) unless
otherwise provided in the certificate of incorporation or bylaws (and unless the
certificate of incorporation directs that a particular class of stock is to
elect such director, in which case any other directors elected by such class, or
a sole remaining director so elected, may fill such vacancy). Under the FCG
Certificate of Incorporation and FCG Bylaws, only a majority of directors then
in office (even though less than a quorum) may fill any vacancies or newly
created directorship on the FCG Board of Directors (unless the FCG Board of
Directors determines by resolution that the newly created directorship shall be
filled by the stockholders).
 
    Pursuant to the PBCL and the ISCG Bylaws, any vacancy on ISCG's Board of
Directors, including vacancies resulting from an increase in the number of
directors, may be filled by a majority vote of the remaining members of the
Board, though less than a quorum, or by a sole remaining director, and each
person so selected will be a director to serve until a successor has been
selected and qualified or until his or her earlier death, resignation or
removal. When one or more directors resign from the board effective at a future
date, the directors then in office, including those who have so resigned, will
have power by the applicable vote to fill the vacancies, the vote thereon to
take effect when the resignations become effective.
 
INTERESTED DIRECTOR TRANSACTIONS
 
    Under the DGCL, certain contracts or transactions in which one or more of a
corporation's directors has an interest are not void or voidable because of such
interest, provided that certain conditions, such as obtaining the required
approval and fulfilling the requirements of good faith and full disclosure are
met. Under the DGCL the conditions are that either (i) the shareholders or the
disinterested directors must approve any such contract or transaction after the
full disclosure of material facts, or (ii) the contract or transaction must have
been fair as to the corporation at the time it was approved. Under the DGCL, if
board approval is sought, the contract or transactions must be approved by a
majority of the disinterested directors (even though less than a quorum).
 
    Similarly, under the PBCL, a transaction between a corporation and an
interested director will not be void or voidable solely for that reason if (i)
the board of directors knows about the director's interest and authorized the
transaction by the affirmative vote of a majority of the disinterested directors
even though the disinterested directors are less than a quorum, (ii) the
shareholders entitled to vote thereon know
 
                                      100
<PAGE>
about the director's interest and the contract is specifically approved in good
faith by vote of those shareholders or (iii) the transaction is fair to the
corporation as of the time it is authorized, approved or ratified by the board
of directors or the shareholders.
 
INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    FCG provides indemnification of its directors, officers and employees. The
FCG Bylaws provide that FCG shall indemnify each of its directors and executive
officers against expenses, judgments, fines, settlements, and other amounts
actually and reasonably incurred in connection with any proceeding, arising by
reason of the fact that such person is or was an agent of the corporation. The
FCG Certificate of Incorporation provides that FCG may agree to indemnify and
protect any director, officer, employee or agent to the fullest extent permitted
by the DGCL. Under the DGCL other than an action brought by or in the right of
the corporation, such indemnification is available if it is determined that the
proposed indemnitee acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceedings, had no reasonable cause to
believe his or her conduct was unlawful. In actions brought by or in the right
of the corporation, such indemnification is limited to expenses actually and
reasonably incurred and permitted only if the indemnitee acted in good faith and
in a manner he or she reasonably believed to be in or not opposed to the best
interests of the company, except that no indemnification may be made in respect
of any claim, issue or matter as to which such person is adjudged to be liable
to the corporation, unless and only to the extent that the court in which the
action was brought determines that, despite the adjudication of liability but in
view of all the circumstances of the case, the person is fairly and reasonably
entitled to indemnity for such expenses which the court deems proper. To the
extent that the proposed indemnitee has been successful in defense of any
action, suit or proceeding, he must be indemnified against expenses actually and
reasonably incurred by him in connection with the action.
 
    The PBCL permits a corporation to indemnify its representatives. Pursuant to
the ISCG Bylaws, no director of ISCG will be personally liable as such for
monetary damages for any action taken, or any failure to take action, unless the
director has breached or failed to perform the duties of his office under the
PBCL and the breach or failure to perform constitutes self-dealing, willful
misconduct or recklessness; provided, however, that a director may be
responsible or liable pursuant to a criminal statute or for payment of taxes
pursuant to local, state or federal law. The ISCG Bylaws provide that ISCG will
indemnify any officer or any director (or employee or agent designated by
majority vote of the ISCG Board of Directors to the extent provided in such
vote) who was or is a party to or threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (including action by or in the right
of ISCG) by reason of the fact that he is or was a director or officer (or
employee or agent) of ISCG or is or was serving at the request of ISCG as a
director or officer (or employee or agent) of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding; provided, however, that indemnification will not be
made in any case where the act or failure to act giving rise to the claim for
indemnification is determined by a court to have constituted willful misconduct
or recklessness. Expenses incurred by an officer, director, employee or agent
purportedly indemnified pursuant to the ISCG Bylaws in defending a civil or
criminal action, suit or proceeding may be paid by the corporation in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such person to repay such amount if it will
ultimately be determined that he is not entitled to be indemnified by the
corporation. The indemnification and advancement of expenses provided for in the
ISCG Bylaws continues as to a person who has ceased to be a director, officer,
employee or agent of the corporation and will inure to the benefit of the heirs,
executors and administrators of such person.
 
                                      101
<PAGE>
AMENDMENTS TO THE CERTIFICATE OF INCORPORATION AND ARTICLES OF INCORPORATION
 
    Under the DGCL, a corporation's certificate of incorporation can be amended
by the affirmative vote of the board of directors and approved by the
affirmative vote of the holders of a majority of the outstanding shares entitled
to vote thereon, unless the certificate of incorporation requires the vote of a
larger portion of the shares. The FCG Certificate of Incorporation requires
approval by 66 2/3% of the outstanding shares entitled to vote thereon in order
to amend certain provisions of the FCG Certificate of Incorporation relating to
the composition of the FCG Board, election, removal and actions of directors,
amendment of the FCG Bylaws and FCG Certificate of Incorporation, actions by
stockholders, the calling of special meetings of stockholders and
indemnification of directors.
 
    The PBCL provides that a vote of the shareholders entitled to vote on a
proposed amendment to the articles of incorporation will be taken at the next
annual or special meeting of which notice for that purpose has been duly given.
Unless the articles of incorporation or a specific provision of the PBCL
requires a greater vote, a proposed amendment of the articles of incorporation
will be adopted upon receiving the affirmative vote of a majority of the votes
cast by all shareholders entitled to vote thereon and, if any class or series of
shares is entitled to vote thereon as a class, the affirmative vote of a
majority of the votes cast in each such class vote. In general, pursuant to the
PBCL, a proposed amendment of the articles of incorporation will not be deemed
to have been adopted by a corporation unless it has also been approved by the
board of directors, regardless of the fact that the board has directed or
suffered the submission of the amendment to the shareholder for action. The ISCG
Articles of Incorporation do not require a higher percentage of affirmative
votes than a majority of the shares entitled to vote thereon.
 
AMENDMENT OF BYLAWS
 
    Under the FCG Certificate of Incorporation and FCG Bylaws, the stockholders
of FCG may alter or amend the FCG Bylaws by a vote of at least 66 2/3% of the
outstanding shares entitled to vote thereon. Under the FCG Certificate of
Incorporation and FCG Bylaws, the FCG Board of Directors may adopt, amend or
repeal the FCG Bylaws.
 
    Pursuant to the PBCL, bylaws of a corporation may be amended or repealed
either by the shareholders of the corporation at any duly organized meeting
thereof or, with respect to those matters that are not expressly committed by
the PBCL to the shareholders and, regardless of whether the shareholders have
previously adopted or approved the bylaws being amended or repeal, by the board
of directors of the corporation.
 
POWER TO CALL SPECIAL SHAREHOLDERS' MEETING; ACTION BY CONSENT
 
    Under the DGCL, a special meeting of stockholders may be called by the board
of directors or by any other person authorized to do so in the certificate of
incorporation or the bylaws. The FCG Certificate of Incorporation and the FCG
Bylaws provide that special meetings of stockholders may be called only by the
FCG Board of Directors, the Chairman of the FCG Board of Directors, the
President of FCG, or by any person or persons holding shares representing at
least 10% of the outstanding capital stock of FCG. The FCG Certificate of
Incorporation provides that any action taken by stockholders must be effected at
an annual or special meeting and may not be effected by written consent.
 
    Under the PBCL, a special meeting of the shareholders may be called at any
time by (i) the board of directors, (ii) unless otherwise provided in the
articles of incorporation, by shareholders entitled to cast at least 20% of the
votes that all shareholders are entitled to cast at that particular meeting or
(iii) by such officers or other persons as may be provided in the bylaws. The
ISCG Bylaws provide that a special meeting of the shareholders may be called at
any time upon written notice to the secretary of the corporation by (i) a
majority of the ISCG Board of Directors or (ii) by the President. Additionally,
under the PBCL and the Bylaws of ISCG, the ISCG Board of Directors must hold at
least one meeting of the shareholders in each calendar year. If the annual
meeting of the shareholders is not called and held within six months after the
time designated by the Board of Directors, then any shareholder may call the
meeting
 
                                      102
<PAGE>
at any time thereafter. The PBCL requires that at any time, upon written request
of any person who has called a special meeting, the secretary must fix the time
of the meeting which, if the meeting is called pursuant to a statutory right,
will be held not more than 60 days after the receipt of the request. If the
secretary neglects or refuses to fix the time of the meeting, the person or
persons calling the meeting may do so.
 
    Under the PBCL, unless otherwise restricted in the bylaws, any action
required or permitted to be taken at a meeting of the shareholders or class of
shareholders of a corporation may be taken without a meeting of the shareholders
if, prior or subsequent to the action, a consent or consents thereto by all the
shareholders who would be entitled to vote at a meeting for such purpose are
filed with the secretary of the corporation. ISCG's Bylaws do not contain any
restrictions on shareholders' ability to act by unanimous written consent. The
PBCL also provides that, if the ISCG bylaws so provide, any action required or
permitted to be taken at a meeting of the shareholders or of a class of
shareholders may be taken without a meeting upon the written consent of
shareholders who would have been entitled to cast the minimum number of votes
that would be necessary to authorize the action at a meeting at which all
shareholders entitled to vote thereon were present and voting. ISCG's Bylaws do
not provide for shareholder action by partial written consent.
 
INSPECTION OF SHAREHOLDERS' LIST
 
    The DGCL allows any shareholder to inspect the shareholders' list for a
purpose reasonably related to such person's interest as a shareholder. The PBCL
provides that the officer or agent having charge of the transfer books for the
shares of the corporation must make a complete list of the shareholders entitled
to vote at a shareholder meeting, arranged in alphabetical order, with the
address of and the number of shares held by each shareholder The list must be
produced and kept open at the time and place of the shareholder meeting and will
be subject to the inspection of any shareholder during the whole time of the
meeting for the purposes thereof.
 
DIVIDENDS AND REPURCHASES OF SHARES
 
    The DGCL permits a corporation, unless otherwise restricted by its
certificate of incorporation, to declare and pay dividends out of its surplus
or, if there is no surplus, out of net profits for the fiscal year in which the
dividend is declared or for the preceding fiscal year as long as the amount of
capital of the corporation is not less than the aggregate amount of the capital
represented by the issued and outstanding stock of all classes having a
preference upon the distribution of assets. The FCG Certificate of Incorporation
does not contain any such restrictions on FCG's ability to declare and pay
dividends. In addition, the DGCL generally provides that a corporation may
redeem or repurchase its shares only if such redemption or repurchase would not
impair the capital of the corporation. The ability of a Delaware corporation to
pay dividends on, or to make repurchases or redemptions of, its shares is
dependent on the financial status of the corporation standing alone and not on a
consolidated basis. In determining the amount of surplus of a Delaware
corporation, the assets of the corporation, including stock of subsidiaries
owned by the corporation, must be valued at their fair market value as
determined by the board of directors, regardless of their historical book value.
 
    The PBCL provides that, unless otherwise restricted in the bylaws, a
distribution may be made unless if, after giving effect thereto, (i) the
corporation would be unable to pay its debts as they become due in the usual
course of its business or (ii) the total assets of the corporation would be less
than the sum of its total liabilities plus the amount that would be needed, if
the corporation were to be dissolved at the time as of which the distribution is
measured, to satisfy the preferential rights upon dissolution of shareholders
whose preferential rights are superior to those receiving the distribution. The
PBCL also permits corporations to acquire their own shares. The ISCG Articles of
Incorporation do not impose additional restrictions on distributions.
Furthermore, the ISCG Articles of Incorporation permit dividends to be paid upon
the ISCG Common Stock as and where declared by the ISCG Board of Directors,
subject to the rights of the
 
                                      103
<PAGE>
preferred shareholders. The ISCG Bylaws provide that any dividends paid may be
paid in cash, in property, or in shares of the corporation.
 
APPROVAL OF CERTAIN CORPORATE TRANSACTIONS
 
    Under the DGCL, with certain exceptions, any merger, consolidation or sale,
lease or exchange of all or substantially all of the assets must be approved by
the board of directors and by the affirmative vote of a majority of the
outstanding shares entitled to vote thereon. Pursuant to the PBCL, a plan of
merger or consolidation generally shall be adopted upon receiving the
affirmative vote of a majority of the votes cast by all shareholders entitled to
vote thereon of each of the domestic corporations that is a party to the merger
or consolidation and, if any class or series of shares is entitled to vote
thereon as a class, the affirmative vote of a majority of the votes cast in each
class to vote. Additionally, the PBCL generally provides that the sale, lease,
exchange or other disposition of all, or substantially all the property and
assets, with or without the goodwill, of a corporation, must be made only
pursuant to a plan of asset transfer which is approved in the same manner that
mergers are approved.
 
BUSINESS COMBINATION FOLLOWING A CHANGE OF CONTROL
 
    The DGCL prohibits certain business combinations between a Delaware
corporation, the shares of which are listed on a national securities exchange,
and an "interested shareholder" for a period of three years following the time
that such person became an "interested shareholder," without board approval,
unless certain conditions are met and unless the certificate of incorporation of
the corporation contains a provision expressly electing not to be governed by
such provisions. The FCG Certificate of Incorporation does not contain such an
election.
 
    Similarly, the PBCL prohibits certain business combinations between a
Pennsylvania corporation that is a "registered corporation" (which includes
corporations registered under the Exchange Act) and an "interested shareholder"
unless certain conditions are met and unless the articles of incorporation
expressly provide that such corporation is electing not to be subject to such
provisions. The ISCG Articles of Incorporation contain such an election,
therefore, provisions of the PBCL that impose special standards with respect to
business combinations between registered corporations and interested
shareholders do not apply to ISCG.
 
SHAREHOLDER DERIVATIVE SUITS
 
    Under the DCGL, a stockholder may only bring a derivative action on behalf
of the corporation if the stockholder was a stockholder of the corporation at
the time of the transaction in question or his or her stock thereafter devolved
upon him or her by operation of law. The PBCL provides that in any action or
proceeding brought to enforce a secondary right on the part of one or more
shareholders of a corporation against any present or former officer or director
of the corporation because the corporation refuses to enforce rights that may
properly be asserted by it, each plaintiff must aver and it must be made to
appear that each plaintiff was a shareholder of the corporation or owner of a
beneficial interest in the shares at the time of the transaction of which he
complains, or that his shares or beneficial interest in the shares devolved upon
him by operation of law from a person who was a shareholder or owner of a
beneficial interest in the shares at that time; provided however that any
shareholder who otherwise would be entitled to maintain the action or proceeding
and who does not meet such requirements may, nevertheless in the discretion of
the court, be allowed to maintain the action or proceeding on preliminary
showing to the court, by application and upon such verified statements and
depositions as may be required by the court, that there is a strong prima facie
case in favor of the claim asserted on behalf of the corporation and that
without the action serious injustice will result. In any action or proceeding
instituted or maintained by holders or owners of less than 5% of the outstanding
shares of any class of the corporation, unless the shares held or owned by the
holders or owners have an aggregate fair market value in excess of $200,000, the
corporation in whose right the action or proceeding is brought will be entitled
to require the plaintiffs to give security for the reasonable expenses,
including attorneys' fees, that may be incurred by it in
 
                                      104

connection therewith or for which it may become liable in connection with
mandatory indemnification, to which security the corporation will have recourse
in such amount as the court determines upon the termination of the action or
proceeding.
 
DISSENTERS' RIGHTS
 
    Under the DGCL, a shareholder of a corporation participating in certain
major corporate transactions may, under varying circumstances, be entitled to
appraisal rights pursuant to which such shareholder may receive cash in the
amount of the fair market value of the shares held by such shareholder (as
determined by a court or by agreement of the corporation and the shareholder) in
lieu of the consideration such shareholder may otherwise receive in the
transaction. Under the DGCL, appraisal rights are not available to: (i)
stockholders with respect to a merger or consolidation by a corporation, the
shares of which are either listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or are held of
record by more than 2,000 holders if such stockholders receive only shares of
the surviving corporation or shares of any other corporation which are either
listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or are held of record by more than 2,000 holders; or
(ii) stockholders of a corporation surviving a merger if no vote of the
stockholders of the surviving corporation is required to approve the merger
because, among other things, the number of shares to be issued in the merger
does not exceed 20% of the shares of the surviving corporation outstanding
immediately prior to the merger, and if certain other conditions are met.
 
    Under the PBCL, a shareholder of a corporation generally has the right,
under varying circumstances, to dissent from certain corporate transactions
(including mergers, share exchanges, the sale of all or substantially all of the
corporate assets and corporate divisions) and to obtain payment in cash of the
fair value of his shares in lieu of the consideration he would otherwise receive
in the transaction. Pursuant to the PBCL, if the proposed corporate action is
submitted to a vote at a meeting of shareholders of a corporation, any person
who wishes to dissent and obtain payment of the fair value of his shares must
file with the corporation, prior to the vote, a written notice of intention to
demand that he be paid the fair value for his shares if the proposed action is
effectuated, must effect no change in the beneficial ownership of his shares
form the date of such filing continuously through the effective date of the
proposed action and must refrain from voting his shares in approval of such
action. A dissenter who fails in any respect will not acquire any right to
payment of the fair value of his shares. Neither a proxy nor a vote against the
proposed corporate action will constitute the written notice required. Under the
PBCL, a person who wishes to exercise dissenters' rights must also comply with
the other requirements set forth in the PBCL. See "Summary of Dissenters'
Rights."
 
    The DGCL also does not provide stockholders of a corporation with appraisal
rights when the corporation acquires another business through the issuance of
its capital stock: (i) in exchange for all or substantially all of the assets of
the business to be acquired; (ii) in exchange for more than fifty percent of the
outstanding shares of the corporation to be acquired; or (iii) in a merger of
the corporation to be acquired with a subsidiary of the acquiring corporation.
 
   
DISSENTERS' RIGHTS MAY BE AVAILABLE TO SHAREHOLDERS OF ISCG WITH RESPECT TO THE
MERGER. SEE "THE MERGER-- RIGHTS OF DISSENTING SHARES OF ISCG."
    
 
DISSOLUTION
 
    Under the DGCL, unless approved by stockholders holding 100% of the total
voting power of the corporation, a dissolution must be initiated by the FCG
Board of Directors and approved by the affirmative vote of the holders of a
majority of the outstanding stock of the corporation entitled to vote thereon.
 
                                      105
<PAGE>
    Under the PBCL, a resolution to dissolve a corporation shall be adopted upon
receiving the affirmative vote of a majority of the votes cast by all
shareholders of the corporation entitled to vote thereon and, if any class of
shares is entitled to vote thereon as a class, the affirmative vote of a
majority of the votes cast in each class vote. A proposal for the voluntary
dissolution of a corporation will not be deemed to have been adopted by the
corporation unless it has also been recommended by resolution of the board of
directors, regardless of the fact that the board has directed or suffered the
submission of such a proposal to the shareholders for action.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Board of Directors
First Consulting Group, Inc.
 
    We have audited the accompanying consolidated balance sheets of First
Consulting Group, Inc. (formerly FCG Enterprises, Inc.) and its subsidiaries as
of December 31, 1997 and 1996, and the related consolidated statements of
operations, changes in stockholders' equity and cash flows for each of the three
years in the period ended December 31, 1997. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
First Consulting Group, Inc. and Subsidiaries as of December 31, 1997 and 1996,
and the consolidated results of their operations and their consolidated cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
NATURE OF BUSINESS
 
    First Consulting Group, Inc. (formerly FCG Enterprises, Inc.) and its
subsidiaries (the "Company") is a leading provider of information technology and
other consulting services for healthcare providers, payors, and other healthcare
organizations. The Company's services are designed to assist its clients in
increasing operations effectiveness by reducing cost, improving customer service
and enhancing the quality of patient care. The Company provides this expertise
to clients by assembling multi-disciplinary teams which provide comprehensive
services across its four principal services: consulting, software
implementation, network and application integration and co-management services.
The Company's services and consultants are supported by internal research and a
centralized information system which provides real-time access to current
industry and technology information, project methodologies, experiences and
tools.
 
    1.  PRINCIPLES OF CONSOLIDATION
 
    The consolidated financial statements include the accounts of First
Consulting Group, Inc. and its wholly-owned subsidiaries. All material
intercompany accounts and transactions have been eliminated.
 
    2.  CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid debt instruments purchased with an
original maturity of three months or less to be cash equivalents.
 
    3.  PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Depreciation and amortization are
provided on a straight-line basis in amounts sufficient to relate the cost of
depreciable assets to operations over their estimated service lives. Leasehold
improvements are amortized over the lives of the respective leases or the
service lives of the improvements, whichever is shorter.
 
    4.  WORK IN PROCESS
 
    Work in process represents the recognized net revenue for services performed
that had not been billed to clients at the balance sheet date. Such amounts are
billed as project requisites are met.
 
    5.  INCOME TAXES
 
    The Company accounts for income taxes on the liability method under which
deferred tax liabilities (assets) are determined based on the differences
between the financial statement and tax bases of assets and liabilities as
measured by the enacted tax rates which will be in effect when these differences
reverse. Deferred tax expense (benefit) is equal to the change in the deferred
tax liability (asset) from the beginning to the end of the year. A current tax
asset or liability is recognized for the estimated taxes refundable or payable
for the current year.
 
    6.  PUT OBLIGATIONS
 
    Currently the existing stockholders of the Company, including the Associate
401(k) and Stock Ownership Plan ("ASOP"), have the ability to require the
Company to repurchase their shares upon the occurrence of certain conditions,
which are outside the control of the Company (see Notes H and I). As such, the
Company reflects estimated obligations related to these repurchase commitments
outside of equity in the accompanying financial statements.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    7.  REVENUE RECOGNITION
 
    The Company generates substantially all of its revenue from fees for
professional services. The Company typically bills for its services on an
hourly, fixed-fee or fixed-fee per month basis. For services billed on an hourly
basis, the Company recognizes revenue as services are performed. For services
billed on a fixed-fee or fixed-fee per month basis, the Company recognizes
revenue using the percentage of completion method. Revenue is recorded as
incurred at assignment rates net of any adjustments due to specific engagement
situations.
 
    8.  STOCK-BASED COMPENSATION
 
    The Company accounts for stock-based employee compensation as prescribed by
APB Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES, and has adopted
the disclosure provisions of Statement of Financial Accounting Standards 123,
ACCOUNTING FOR STOCK-BASED COMPENSATION ("SFAS 123"). SFAS 123 requires pro
forma disclosures of net income and net income per share as if the fair value
based method of accounting for stock-based awards had been applied. Under the
fair value based method, compensation cost is recorded based on the value of the
award at the grant date and is recognized over the service period. The adoption
of SFAS 123 disclosure provisions has no effect on either the Company's
financial condition or its results of operations.
 
    9.  BASIC AND DILUTED NET INCOME (LOSS) PER SHARE
 
   
    Net income (loss) per share is calculated in accordance with Statement of
Financial Accounting Standards No. 128, EARNINGS PER SHARE ("SFAS 128"), which
superseded APB Opinion No. 15. Net income (loss) per share for all periods
presented has been restated to reflect the adoption of SFAS 128. Basic net
income (loss) per share is based upon the weighted average number of common
shares outstanding. Diluted net income (loss) per share is based on the
assumption that all convertible shares and stock options were converted or
exercised. Dilution is computed by applying the treasury stock method. Under
this method, options and warrants are assumed to be exercised at the beginning
of the period (or at the time of issuance, if later), and as if funds obtained
thereby were used to purchase Common Stock at the average market price during
the period. ASOP shares that have not been committed to be released are not
treated as outstanding when determining the weighted average number of shares
for either basic or diluted net income (loss) per share.
    
 
    The Company previously issued financial statements that presented net income
(loss) per share in accordance with Securities and Exchange Commission Staff
Accounting Bulletin (SAB) No. 83, which was subsequently superceded by SAB No.
98. The financial statements have been restated to conform to the guidance in
SAB No. 98.
 
    10.  CREDIT RISKS
 
    Financial instruments that subject the Company to concentrations of credit
risks consist primarily of billed and unbilled accounts receivable. The
Company's clients are primarily involved in the healthcare industry.
Concentrations of credit risk with respect to billed and unbilled accounts
receivable are limited due to the Company's credit evaluation process and the
nature of its clients. Historically, the Company has not incurred significant
credit-related losses.
 
    11.  FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    Management believes the fair value of financial instruments approximates
their carrying amounts. The carrying value of cash and cash equivalents
approximates their estimated fair values. Management believes

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE A--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
the fair values of notes payable and stockholders' notes receivable approximate
their carrying values based on current rates for instruments with similar
characteristics.
 
    12.  UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET
 
    The Company is in the process of modifying its stock agreements such that,
upon the effectiveness of the proposed initial public offering, the Company will
no longer have the obligation to repurchase shares of Common Stock from the
current stockholders. A pro forma unaudited consolidated balance sheet as of
December 31, 1997 has been presented to reflect this change.
 
    13.  DEFERRED COMPENSATION--STOCK INCENTIVE AGREEMENTS
 
    In accordance with APB Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO
EMPLOYEES, the Company records a charge to deferred compensation when it grants
options or sells stock to officers or employees at an exercise price which is
less than the fair market value of such shares. Amounts recorded as deferred
compensation are amortized over the appropriate service period based upon the
vesting schedule for such grants (generally ten years).
 
    14.  USE OF ESTIMATES
 
    In preparing financial statements in conformity with generally accepted
accounting principles, management is required to make estimates and assumptions
that affect the reported amounts of assets and liabilities, the disclosure of
contingent assets and liabilities at the date of the financial statements, and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
    15.  NEW ACCOUNTING PRONOUNCEMENTS
 
    In 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 130 ("SFAS 130"), REPORTING COMPREHENSIVE
INCOME, which prescribes standards for reporting comprehensive income and its
components. Comprehensive income consists of net income or loss for the current
period and other comprehensive income (income, expenses, gains and losses that
currently bypass the income statement and are reported directly in a separate
component of equity). SFAS 130 is effective for financial statements issued for
periods beginning after December 15, 1997. The Company has determined that the
adoption of SFAS 130 will not have a material effect on the Company's financial
statements.
 
    In 1997, the FASB issued Statement of Financial Accounting Standards No. 131
("SFAS 131"), DISCLOSURES ABOUT SEGMENTS OF AN ENTERPRISE AND RELATED
INFORMATION, which applies only to publicly held business entities. A reportable
segment, referred to as an operating segment, is component of an entity about
which separate financial information is produced internally, that is evaluated
by the chief operation decision-maker to assess performance and allocate
resources. SFAS 131 is effective for financial statements issued for periods
beginning after December 15, 1997.
 
    16.  RECLASSIFICATIONS
 
    Certain reclassifications have been made to the 1996 and 1995 financial
statements to conform to the 1997 presentation.

NOTE B--NOTES PAYABLE
 
    The Company has a $6,000,000 revolving line of credit available through
December 1, 1998, at the bank's prevailing prime rate. The balance outstanding
on this line of credit was $2,000,000 and zero at December 31, 1997 and 1996,
respectively. Borrowings on the line are collaterized by all of the Company's
deposit accounts, accounts receivable and equipment. Under the line of credit
agreement, the Company is required to pay a fee equal to 0.25% per annum on the
average daily unused balance and maintain selected financial ratios.
 
    Long-term debt is summarized as follows (in thousands):

    For tax reporting purposes, the Company had historically elected to be taxed
under the cash basis of reporting as opposed to the accrual method used for
financial reporting purposes. As a result of such election, a deferred tax
liability of $6,016,000 and $4,404,000 exists at December 31, 1997 and 1996,
respectively. As a result of the proposed initial public offering of Common
Stock, the Company is required to change its tax reporting to the accrual basis
to be consistent with financial reporting purposes. As a

NOTE C--INCOME TAXES (CONTINUED)
result of this change, the deferred tax liability resulting from the use of cash
basis reporting for income taxes will become payable over a period not exceeding
four years.
 
NOTE D--NOTES RECEIVABLE--STOCKHOLDERS
 
    Notes receivable from stockholders consist primarily of loans provided to
participants of the restricted stock bonus and non-qualified stock option
agreements (see Note H). The Company allows participants to exchange notes for
the purchase of shares of Common Stock and the exercise of stock options. Notes
received in exchange for Common Stock have been classified as a reduction of
stockholders' equity. In addition, the Company also provides participants with
notes to cover associated taxes related to the exercise of stock options. Notes
are generally non-recourse and non-interest bearing and have been discounted
using imputed annual interest rates from 5.77% to 6.36%. Such notes are payable
over a ten-year term.
 
    Participants are required to pay, each year, the greater of 10% of the
outstanding amounts or 50% of the after tax amount of any annual bonus received
by them to repay outstanding amounts of the notes. Stockholders' notes
receivable received in exchange for Common Stock were $5,134,000 and $2,043,000,
as of December 31, 1997 and 1996, respectively. Amortization of deferred
compensation resulting from discounting the face value of non-interest bearing
notes issued to the Company by its vice presidents for the purchase of shares of
Common Stock was $266,269 and $93,432 for the years ended December 31, 1997 and
1996, respectively. Stockholders' notes receivable related to advances to
associates for payment of taxes associated with stock option exercises were
$1,679,000 and $454,000 as of December 31, 1997 and 1996, respectively.
Compensation expense resulting from discounting the face value of non-interest
bearing notes issued to the Company by its vice presidents in connection with
the Company's payment of certain tax liabilities relating to the exercise of
stock options was $518,855 and $187,425 for the years ended December 31, 1997
and 1996, respectively.

    None of the options outstanding at December 31, 1997 are exercisable. As of
December 31, 1997, option prices ranged from $4.76 to $7.44 and had a remaining
weighted average life of 9.73 years.
 
    Adjusted pro forma information regarding net income is required by SFAS 123,
and has been determined as if the Company had accounted for its employee stock
options under the fair value method of that Statement. The fair value for these
options was estimated at the date of grant using the "minimal value" method for
option pricing with the following weighted average assumptions: risk-free
interest rate of 6%; dividend yield of 0%; and a remaining weighted average life
of the option of two to five years. For purposes of adjusted pro forma
disclosures, the estimated fair value of the options is not materially different
from the intrinsic value of the options. As such, the pro forma impact on
reported results for the years ended December 31, 1997, 1996 and 1995 was not
significant and has not been presented herein. The weighted average fair value
of options granted during the year ended December 31, 1997, 1996 and 1995 was
$1.60, $2.79 and $1.13, respectively.
 
    For the year ended December 31, 1997, 1996 and 1995, compensation expense
recognized in income for stock-based employee compensation related to the grant
of options was $278,415, $215,000 and $385,000, respectively.

NOTE G--PROFIT-SHARING PLAN AND SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN
 
PROFIT-SHARING PLAN
 
    The Company had a discretionary profit-sharing plan covering substantially
all employees. Contributions were determined by the Board of Directors and were
limited to the maximum amount deductible for federal income tax purposes.
Discretionary contributions to the profit-sharing plan were $150,000 for the
year ended December 31, 1995. Effective January 1, 1996, this plan was merged
into the ASOP (see Note I).
 
SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN
 
    On January 1, 1994 the Company adopted the Supplemental Executive Retirement
Plan (the "SERP"). The SERP was amended on January 1, 1996. The SERP is
administered by the Board of Directors or a committee appointed by the Board of
Directors.
 
    Participants in the SERP are those executive officers at the vice president
or higher level of seniority who are eligible to participate in the 1994 Plan
and who are selected by the Board of Directors or a committee appointed by the
Board of Directors to participate. The Board of Directors or a committee
appointed by the Board of Directors may also designate other officers for
participation in the compensation reduction portion of the SERP. Participation
is conditioned on the submission of a completed enrollment form. SERP
participation terminates when a participant ceases to be a stockholder of the
Company, provided that a former stockholder who continues as an officer may
continue to participate in the compensation reduction portion of the SERP.
 
    Participants may make fully vested compensation reduction contributions to
the SERP, subject to a maximum deferral of 10% of annual base salary. The
Company may make a voluntary "FCG Contribution" for any year in an amount
determined by the Board to the account of SERP participants. FCG Contributions
vest 10% for each year of service (with up to 5 years service credit for
participants who were vice presidents on January 1, 1994), provided that FCG
Contributions fully vest upon a Change in Control of the Company or upon a
participant's death, disability or attainment of age 65. Company contributions
to the SERP were $493,000, $372,000 and $301,000 for the years ended December
31, 1997, 1996, and 1995, respectively.
 
    The contributions to the SERP are invested by the Company in Variable Life
Insurance Contracts. Management believes that the participants' account balance,
cash surrender value of life insurance and death benefits will be sufficient to
satisfy the Company's obligations under the SERP.

1994 RESTRICTED STOCK PLAN AND AGREEMENTS
 
    On December 15, 1997, the Board of Directors adopted an amendment to the
1994 Restricted Stock Plan (as amended the "1994 Plan") and form of Restricted
Stock Agreement ("RSA"). The stockholders approved the 1994 Plan and RSAs on
January 15, 1998. The 1994 Plan provides a mechanism for the purchase and sale
of Common Stock by its vice presidents. The 1994 Plan is administered by the
Company's Board of Directors or a committee appointed by the Board.
 
    Under the 1994 Plan, the Company has entered into RSAs with each of its vice
presidents. The 1994 Plan and RSAs provide that each person, upon becoming a
vice president of the Company, must purchase and hold a specific minimum number
of shares of Common Stock. Vice presidents at Levels I and II are

NOTE H--STOCK INCENTIVE AGREEMENTS (CONTINUED)
required to purchase and hold that number of shares equal to one times the vice
president's base salary divided by the then-current fair value of the Common
Stock. Vice presidents at Levels III and IV are required to purchase and hold
that number of shares equal to two times the vice president's base salary
divided by the then-current fair value of the Common Stock. Prior to the
completion of this offering, the fair value of the Common Stock is determined by
reference to a report prepared for the Company by an independent valuation firm.
 
    Shares purchased under the RSAs are subject to a 10-year vesting period
beginning the date upon which an individual becomes a vice president and vest
annually upon the completion of each year of service. Automatic acceleration of
vesting occurs upon death or permanent disability of a vice president and upon
certain changes in ownership of the Company. Partial acceleration of vesting may
also occur once the vice president attains the age of 59. Shares purchased after
consummation of this offering are fully vested upon purchase.
 
    Under the terms of the RSAs, the Company retains a repurchase right with
respect to unvested shares, unless such termination is due to debt, disability
or changes in control of the Company. Pursuant to this right, the Company may
repurchase unvested shares at the original issuance price plus a growth factor.
The growth factor is equal to the average interest rate compounded quarterly
which the Company pays to a commercial lending institution in a calendar quarter
(the "Growth Factor"). In the event the Company has no borrowings for a
particular quarter, then the Growth Factor shall be the prime rate on the first
day of the quarter, as announced in the Wall Street Journal or if the Wall
Street Journal discontinues such announcements, then it shall be the prime rate
as announced by Bank of America. Shares acquired under RSAs are nontransferable,
with the exception of transfers for certain estate planning and charitable gift
purposes. In addition, the RSAs provide that, under certain circumstances and
upon attaining a certain age, a vice president may sell a portion, but not all,
of his or her shares to other vice presidents or to the Company. The Company may
also repurchase vested shares from a departing vice president if he or she
competes with the Company and/or profits from the sale of Common Stock within
six months of such competition. Upon completion of this offering, a vice
president may also sell unencumbered shares of Common Stock on the public
market, subject to continuing to satisfy the minimum shareholding requirements.
Vice presidents pay the purchase price of the shares by means of non-recourse
and recourse non-interest bearing promissory notes.
 
    The RSAs also contain non-competition and non-solicitation provisions which
apply generally to the vice president's employment with the Company and which
continue to bind the vice president even after repurchase of all shares by the
Company; provided, however, that such provisions may be superseded by an
employment agreement entered into between the Company and the vice president.
 
    The Company maintains life insurance coverage for the purpose of redeeming
stock of its vice president stockholders through the SERP in the event of a vice
president's death (see Note G). For most vice presidents, the insured benefit is
equal to the current market value of the vice president's shareholdings. The
Company is also the beneficiary of a split-dollar life insurance policy on its
principal stockholder that is intended to partially fund the repurchase of the
principal stockholder's stock upon death. The Company also maintains long-term
disability insurance policies on the principal stockholder to help fund the
purchase of stock upon permanent disability of the stockholder.

NOTE H--STOCK INCENTIVE AGREEMENTS (CONTINUED)
NON-QUALIFIED STOCK OPTION AGREEMENT
 
    Effective January 1, 1996, and restated January 1, 1997, the Company
executed and adopted a non-qualified stock option agreement for certain
officers. The principal terms of the agreement provide that for each share of
stock purchased at fair market value, the stockholder is granted one exercisable
stock option which allows the stockholder to purchase additional shares at a
price below the fair market value of the Common Stock. During 1997 and 1996,
215,176 and 366,168 shares, respectively, were granted under the provisions of
the agreement and stockholders exercised options on 822,424 and 193,928 shares
of Common Stock, respectively. Deferred compensation of $512,000 and $737,000
was recorded for the years ended December 31, 1997 and 1996, respectively,
related to the granting of options under this agreement. Compensation expense
related to the amortization of the deferred compensation on these options
approximated $145,000 and $79,000 for the years ended December 31, 1997 and
1996, respectively.
 
    Effective December 19, 1995, the Company executed and adopted a
non-qualified stock option agreement for certain vice presidents. The principal
terms of the agreement provided that for each share of stock purchased at fair
market value of the Common Stock, the stockholder was granted two exercisable
stock options which allow the stockholder to purchase additional shares at
approximately 20% of the fair market value of the Common Stock. During 1995,
1,279,440 stock options were granted under the provisions of the agreement and
vice presidents exercised options for 733,008 shares of Common Stock.
Compensation expense related to these options approximated $134,000, $136,000
and $385,000 for the years ended December 31, 1997, 1996 and 1995, respectively.
The agreements also provide that the Company will make non-recourse loans
available for the purchase of stock, the exercise of stock options and
associated taxes (see Note D).
 
OTHER EQUITY PLANS
 
    On August 22, 1997, the Board adopted an equity incentive plan and
non-employee directors' stock option plan, which was approved by the
shareholders on January 15, 1998. The principal terms of the equity incentive
plan allow the Company to grant either stock options, stock bonuses or stock
appreciation rights to acquire up to 1,600,000 shares of Common Stock. The stock
awards vest over a ten-year term from the date of grant. Under the plan, the
Company granted employees 945,400 options to purchase Common Stock at an
exercise price equal to the market price of Common Stock on the date of grant.
As of December 31, 1997, none of these options were exercisable. The Company had
no stock appreciation rights issued or outstanding for the year ended December
31, 1997.
 
    The non-employee directors' stock option plan allows the Company to grant
options under such plan for up to 200,000 shares of Common Stock. Under the
plan, the Company granted 84,000 options on August 22, 1997, to purchase Common
Stock at an exercise price equal to the market price of the Common Stock on date
of grant. These options vest over a ten-year term from date of grant.
 
NOTE I--ASSOCIATE 401(k) AND STOCK OWNERSHIP PLAN
 
    The ASOP, as amended, was adopted effective December 1, 1995. The ASOP
covers all employees of the Company and affiliates of the Company designated by
the Company's Board of Directors, excluding any union employees unless their
coverage is bargained for, and excluding non-resident aliens without U.S. source
earned income. ASOP participation commences automatically for newly eligible
employees on semiannual entry dates.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE I--ASSOCIATE 401(k) AND STOCK OWNERSHIP PLAN (CONTINUED)
    Under the ASOP, participants may elect to reduce their current compensation
by up to the lesser of 15% of such compensation or the statutorily prescribed
annual limit ($9,500 in 1997) and have the amount of such reduction contributed
to the ASOP. In addition, the Company may make contributions to the ASOP on
behalf of participants. Company contributions may be matching contributions
allocated based on each participant's compensation reduction contributions,
discretionary profit sharing contributions allocated based on each participant's
compensation, or "first share contributions" allocated to some or all
participants on a per capita basis.
 
    The ASOP is intended to qualify under Section 401 of the Internal Revenue
Code of 1986, as amended, so that contributions by employees or by the Company
to the ASOP, and income earned thereon are not taxable until withdrawn and so
that contributions by the Company, if any, will be deductible by the Company
when made. Participants become vested in Company contributions under two graded
vesting schedules, so that matching and first share contributions are fully
vested after five years of service and profit sharing contributions are fully
vested after seven years of service. The ASOP is a leveraged employee stock
ownership plan. The ASOP borrowed $4.0 million from a third-party financial
institution (the "ASOP Loan") to purchase 1,429,848 shares of Common Stock in
1995. The shares of Common Stock so purchased were placed in a suspense account
under the ASOP from which they are released and allocated to participants
accounts' as the ASOP Loan is repaid. Any or all Company contributions may be
used to repay the ASOP Loan.
 
    The Company accounts for its ASOP in accordance with Statement of Position
93-6, EMPLOYERS' ACCOUNTING FOR EMPLOYEE STOCK OWNERSHIP PLANS. Accordingly, the
Company reports in its Statement of Financial Position the debt of the ASOP and
unearned ASOP shares, which is the original cost basis of the ASOP shares
pledged as collateral for the debt. As shares are committed to be released, the
Company credits unearned ASOP shares based on the cost of the shares to the
ASOP. The Company records compensation expense based on the fair market value of
the shares committed to be released. The difference between the fair value of
shares committed to be released and the cost of those shares to the ASOP is
either charged or credited to stockholders' equity accounts, as applicable.
Compensation expense for the 401(k) match and the ASOP was approximately $2.4
million and $1.8 million for the years ended December 31, 1997 and 1996,
respectively. No compensation expense related to the ASOP was recognized in 1995
as the plan was adopted on December 1, 1995 and none of the shares had been
committed to be released. Prior to the adoption of the ASOP, the Company
sponsored a profit-sharing plan which included a 401(k) provision with
essentially the same provisions as the current ASOP. The Company's matching
contributions to the 401(k) provision under the previous profit sharing plan was
$560,000 during 1995.
 
    In 1996, the Company made matching contributions and first share
contributions to the ASOP sufficient to provide a 50% matching contribution and
a first share contribution of 200 shares of Company stock for each participant
who was employed by the Company on January 1, 1996 or became employed by the
Company thereafter. In consideration for employees allowing the Company to make
a plan modification to the current ASOP plan, the Company committed to release
1,000 shares of Common Stock to each participant in the ASOP as of November 26,
1997 (568,000 shares in the aggregate). This commitment resulted in a charge to
compensation expense of approximately $4.2 million in the fourth quarter of
1997. Such amount is included in compensation expenses related to stock
issuances in the accompanying financial statements. The committed shares will be
released to participant accounts to the extent that shares distributed to an
individual do not exceed certain Internal Revenue Service section limitations.

    Upon the cessation of employment of an employee, the Company pays the
employee the fair market value of the shares of Common Stock previously
allocated to such employee under the ASOP. The fair market value of Common Stock
is determined by an independent valuation firm. The ultimate funding of this
obligation rests with the Company. Accordingly, the Company has recorded the
potential future obligation to repurchase such securities outside of permanent
equity (see also Note H). Subsequent to the Company's closing of its anticipated
initial public offering, shares of Common Stock held by the ASOP are expected to
be tradable on an established exchange and recording of such amounts outside of
permanent equity will no longer be required (see Note A-11).
 
NOTE J--CONCENTRATION OF CREDIT RISK
 
    The Company maintains its cash balances in a financial institution located
in Long Beach, California. These balances are insured by the Federal Deposit
Insurance Corporation up to $100,000. At December 31, 1997, the Company had
balances in excess of the insured amount of approximately $3,940,000. The
Company has not experienced any losses in such account and believes it is not
exposed to any significant credit risk on its cash and cash equivalents. The
Company has concentrations of credit risk related to accounts receivable and
revenues. At December 31, 1997, accounts receivable associated with five clients
represented approximately 30% of the accounts receivable balance. Also, for the
year ended December 31, 1997, approximately 15% of total net revenue was
attributable to five clients.
 
NOTE K--SUBSEQUENT EVENT
 
    The Board of Directors authorized management of the Company to file a
registration statement with the Securities and Exchange Commission permitting
the Company to sell up to 6,000,000 shares of Common Stock to the public (the
"Offering"). In connection with the Offering, the Board of Directors approved a
four-for-one stock split in the form of a stock dividend covering all of the
Company's capital stock and options. All share and per share amounts included in
the accompanying financial statements have been adjusted to reflect the stock
split. In conjunction with the Offering, the Board of Directors authorized,
subject to shareholder approval, the reincorporation of the Company into
Delaware, resulting in a change in the Company's name from FCG Enterprises, Inc.
to First Consulting Group, Inc.

               NOTES TO INTERIM CONSOLIDATED FINANCIAL STATEMENTS
 
1. BASIS OF PRESENTATION
 
    The consolidated balance sheets of First Consulting Group, Inc. (the
"Company") at June 30, 1998 and 1997 and consolidated statements of operations
and condensed consolidated statements of cash flows for the periods ended June
30, 1998 and 1997 are unaudited. These financial statements reflect all
adjustments, consisting of only normal recurring adjustments, which, in the
opinion of management, are necessary to fairly present the financial position of
the Company at June 30, 1998 and the results of operations for the three month
periods ended June 30, 1998 and June 30, 1997, and the six month periods ended
June 30, 1998 and June 30, 1997. The results of operations for the six months
ended June 30, 1998 are not necessarily indicative of the results to be expected
for the year ending December 31, 1998. For more complete financial information,
these financial statements should be read in conjunction with the audited
financial statements for the year ended December 31, 1997 included in the
Company's Registration Statement on Form S-1, File No. 333-41121, declared
effective on February 12, 1998.

state of Delaware forming First Consulting Group, Inc. and authorizing
50,000,000 shares of Common Stock and authorizing 10,000,000 shares of preferred
stock. On January 22, 1998, the Board of Directors of FCG Enterprises, Inc., a
California company, approved a 4-for-1 split of Common Stock in the form of a
stock dividend. On February 10, 1998, FCG Enterprises, Inc., a California

months or less. Securities available for sale are measured at fair value, with
net unrealized holding gains and losses, net of tax, reported as a net amount as
a separate component of stockholders' equity. The Company has approximately $9.9
million in short term investments and $25.7 in non-current investments
classified as available for sale. Such investments are currently held primarily
in tax-exempt government securities.

may be specified in the Articles of Merger (the "EFFECTIVE TIME").
 
    1.4  CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND
OFFICERS.  Unless otherwise determined by Parent prior to the Effective Time:
 
        (a) the Articles of Incorporation and Bylaws of the Surviving
    Corporation shall be amended and restated as of the Effective Time to
    conform to the Amended and Restated Articles of Incorporation and Amended
    and Restated Bylaws substantially in the form attached hereto as Exhibits
    F-1 and F-2, respectively; PROVIDED, HOWEVER, that at the Effective Time the
    Articles of Incorporation of the Surviving Corporation shall be amended so
    that the name of the Surviving Corporation shall be Integrated Systems
    Consulting Group, Inc.; and
 
        (b) the directors and officers of the Surviving Corporation immediately
    after the Effective Time shall be the directors and officers of Merger Sub
    immediately prior to the Effective Time, until their respective successors
    are elected and qualified or duly appointed, as the case may be.
 
    1.5  CONVERSION OF SHARES.
 
        (a) Subject to Section 1.5(d), at the Effective Time, by virtue of the
    Merger and without any further action on the part of Parent, Merger Sub, the
    Company or any shareholder of the Company:
 
            (i) any shares of Company Common Stock then held by the Company or
       any subsidiary of the Company (or held in the Company's treasury) shall
       be canceled;
 
            (ii) any shares of Company Common Stock then held by Parent, Merger
       Sub or any other subsidiary of Parent shall be canceled;
 
           (iii) except as provided in clauses "(i)" and "(ii)" above and
       subject to Sections 1.5(b) and (d) and Section 1.9, each share of Company
       Common Stock then outstanding shall be converted into the right to
       receive 0.77 of a share of Parent Common Stock; and
 
   
            (iv) each share of the Common Stock, no par value per share, of
       Merger Sub then outstanding shall be converted into one share of Common
       Stock of the Surviving Corporation.
    
 
        (b) The fraction of a share of Parent Common Stock into which each
    outstanding share of Company Common Stock is to be converted pursuant to
    Section 1.5(a)(iii) (as such fraction may be adjusted in accordance with
    this Section 1.5(b)) is referred to as the "EXCHANGE RATIO." If, between the
    date of this Agreement and the Effective Time, the outstanding shares of
    Company Common Stock or Parent Common Stock are changed into a different
    number or class of shares by reason of any stock split, stock dividend,
    reverse stock split, reclassification, recapitalization or other similar
    transaction, then the Exchange Ratio shall be appropriately adjusted.
 
                                      A-2
<PAGE>
        (c) If any shares of Company Common Stock outstanding immediately prior
    to the Effective
    Time are unvested or are subject to a repurchase option, risk of forfeiture
    or other condition under any applicable restricted stock purchase agreement
    or other agreement with the Company, then the shares of Parent Common Stock
    issued in exchange for such shares of Company Common Stock will also be
    unvested and subject to the same repurchase option, risk of forfeiture or
    other condition, and the certificates representing such shares of Parent
    Common Stock may accordingly be marked with appropriate legends. The Company
    shall take all action that may be necessary to ensure that, from and after
    the Effective Time, Parent is entitled to exercise any such repurchase
    option or other right set forth in any such restricted stock purchase
    agreement or other agreement.
 
        (d) No fractional shares of Parent Common Stock shall be issued in
    connection with the Merger, and no certificates for any such fractional
    shares shall be issued. In lieu of such fractional shares, any holder of
    Company Common Stock who would otherwise be entitled to receive a fraction
    of a share of Parent Common Stock (after aggregating all fractional shares
    of Parent Common Stock issuable to such holder) shall, upon surrender of
    such holder's Company Stock Certificate(s) (as defined in Section 1.7), be
    paid in cash the dollar amount (rounded to the nearest whole cent), without
    interest, determined by multiplying such fraction by the closing price of a
    share of Parent Common Stock on Nasdaq on the Effective Date.
 
    1.6  STOCK OPTIONS AND WARRANTS.  At the Effective Time, all Company Options
(as defined in Section 2.3(b)) shall be assumed by Parent in accordance with
Section 5.5, and all Company Warrants (as defined in Section 2.3(c)) shall be
assumed by Parent in accordance with Section 5.7.
 
    1.7  CLOSING OF THE COMPANY'S TRANSFER BOOKS.  At the Effective Time: (a)
all shares of Company Common Stock outstanding immediately prior to the
Effective Time shall automatically be canceled and retired and shall cease to
exist, and all holders of certificates representing shares of Company Common
Stock that were outstanding immediately prior to the Effective Time shall cease
to have any rights as shareholders of the Company; and (b) the stock transfer
books of the Company shall be closed with respect to all shares of Company
Common Stock outstanding immediately prior to the Effective Time. No further
transfer of any such shares of Company Common Stock shall be made on such stock
transfer books after the Effective Time. If, after the Effective Time, a valid
certificate previously representing any of such shares of Company Common Stock
(a "COMPANY STOCK CERTIFICATE") is presented to the Exchange Agent (as defined
in Section 1.8) or to the Surviving Corporation or Parent, such Company Stock
Certificate shall be canceled and shall be exchanged as provided in Section 1.8.
 
    1.8  EXCHANGE OF CERTIFICATES.
 
        (a) Prior to the Closing Date, Parent shall select a reputable bank or
    trust company to act as exchange agent in the Merger (the "EXCHANGE AGENT").
    Promptly after the Effective Time, Parent shall deposit with the Exchange
    Agent (i) certificates representing the shares of Parent Common Stock
    issuable pursuant to this Section 1 and (ii) cash sufficient to make
    payments in lieu of fractional shares in accordance with Section 1.5(d). The
    shares of Parent Common Stock and cash amounts so deposited with the
    Exchange Agent, together with any dividends or distributions received by the
    Exchange Agent with respect to such shares, are referred to collectively as
    the "EXCHANGE FUND."
 
        (b) As soon as practicable after the Effective Time, the Exchange Agent
    will mail to the registered holders of Company Stock Certificates (i) a
    letter of transmittal in customary form and containing such provisions as
    Parent may reasonably specify (including a provision confirming that
    delivery of Company Stock Certificates shall be effected, and risk of loss
    and title to Company Stock Certificates shall pass, only upon delivery of
    such Company Stock Certificates to the Exchange Agent), and (ii)
    instructions for use in effecting the surrender of Company Stock
    Certificates in exchange for certificates representing Parent Common Stock.
    Subject to Section 1.5(d), upon surrender of a Company Stock Certificate to
    the Exchange Agent for exchange, together with a duly executed letter of
    transmittal and such other documents as may be reasonably required by the
 
                                      A-3
<PAGE>
    Exchange Agent or Parent, (A) the holder of such Company Stock Certificate
    shall be entitled to receive in exchange therefor a certificate representing
    the number of shares of Parent Common Stock that such holder has the right
    to receive pursuant to the provisions of Section 1.5(a)(iii) together with
    any cash in lieu of fractional share(s) pursuant to the provisions of
    Section 1.5(d), and (B) the Company Stock Certificate so surrendered shall
    be canceled. Until surrendered as contemplated by this Section 1.8(b), each
    Company Stock Certificate shall be deemed, from and after the Effective
    Time, to represent only the right to receive shares of Parent Common Stock
    (and cash in lieu of any fractional share of Parent Common Stock) as
    contemplated by Section 1.5. If any Company Stock Certificate shall have
    been lost, stolen or destroyed, Parent may, in its discretion and as a
    condition precedent to the issuance of any certificate representing Parent
    Common Stock, require the owner of such lost, stolen or destroyed Company
    Stock Certificate to provide an appropriate affidavit and to deliver a bond
    (in such sum as Parent may reasonably direct) as indemnity against any claim
    that may be made against the Exchange Agent, Parent or the Surviving
    Corporation with respect to such Company Stock Certificate.
 
        (c) No dividends or other distributions declared or made with respect to
    Parent Common Stock with a record date after the Effective Time shall be
    paid to the holder of any unsurrendered Company Stock Certificate with
    respect to the shares of Parent Common Stock represented thereby, until such
    holder surrenders such Company Stock Certificate in accordance with this
    Section 1.8 (at which time such holder shall be entitled to receive all such
    dividends and distributions, without interest).
 
        (d) Any portion of the Exchange Fund that remains undistributed to
    holders of Company Stock Certificates as of the date 180 days after the date
    on which the Merger becomes effective shall be delivered to Parent upon
    demand, and any holders of Company Stock Certificates who have not
    theretofore surrendered their Company Stock Certificates in accordance with
    this Section 1.8 shall thereafter look only to Parent for satisfaction of
    their claims for Parent Common Stock, cash in lieu of fractional shares of
    Parent Common Stock and any dividends or distributions with respect to
    Parent Common Stock.
 
        (e) Each of the Exchange Agent, Parent and the Surviving Corporation
    shall be entitled to deduct and withhold from any consideration payable or
    otherwise deliverable pursuant to this Agreement to any holder or former
    holder of Company Common Stock such amounts as may be required to be
    deducted or withheld therefrom under the Code or under any provision of
    state, local or foreign tax law or under any other applicable Legal
    Requirement. To the extent such amounts are so deducted or withheld, such
    amounts shall be treated for all purposes under this Agreement as having
    been paid to the Person to whom such amounts would otherwise have been paid.
 
        (f) Neither Parent nor the Surviving Corporation shall be liable to any
    holder or former holder of Company Common Stock with respect to any shares
    of Parent Common Stock (or dividends or distributions with respect thereto),
    or for any cash amounts, delivered to any public official pursuant to any
    applicable abandoned property, escheat or similar Legal Requirement.
 
    1.9  DISSENTING SHARES.  Notwithstanding anything in this Agreement to the
contrary, shares, if any, of Company Common Stock that are issued and
outstanding immediately prior to the Effective Time that are held by any
shareholder who has not voted such shares in favor of the Merger and who shall
have delivered a written notice of intention to demand payment of fair value of
such shares in the manner provided in Section 1574 of the PBCL ("DISSENTING
SHARES") shall not be converted into or be exchangeable for the right to receive
the consideration provided in Section 1.5(a)(iii) (or cash in lieu of fractional
shares in accordance with Section 1.5(d)) unless and until such holder shall
have failed to perfect or shall have effectively withdrawn or lost his right to
be paid fair value under the PBCL. If such holder shall have failed to perfect
or have effectively withdrawn or lost such right, his shares of Company Common
Stock shall thereupon be deemed to have been converted into and to have become
exchangeable for, at the Effective
 
                                      A-4
<PAGE>
Time, the right to receive the consideration provided in Section 1.5(a)(iii) (or
cash in lieu of fractional shares in accordance with Section 1.5(d)) without any
interest thereon.
 
    1.10  TAX CONSEQUENCES.  For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of the
Code. The parties to this Agreement hereby adopt this Agreement as a "plan of
reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the
United States Treasury Regulations.
 
    1.11  ACCOUNTING CONSEQUENCES.  For accounting purposes, the Merger is
intended to be treated as a "pooling of interests."
 
    1.12  FURTHER ACTION.  If, at any time after the Effective Time, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full right,
title and possession of and to all rights and property of Merger Sub and the
Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the Company
and otherwise) to take such action.

    Acquired Corporation in respect of any material Tax. There are no
    unsatisfied liabilities for material Taxes (including liabilities for
    interest, additions to tax and penalties thereon and related expenses) with
    respect to any notice of deficiency or similar document received by any
    Acquired Corporation with respect to any material Tax (other than
    liabilities for Taxes asserted under any such notice of deficiency or
    similar document which are being contested in good faith by the Acquired
    Corporations and with respect to which adequate reserves for payment have
    been established). There are no liens for material Taxes upon any of the
    assets of any of the Acquired Corporations except liens for current Taxes
    not yet due and payable. None of the Acquired Corporations has entered into
    or become bound by any agreement or consent pursuant to Section 341(f) of
    the Code. None of the Acquired Corporations has been, and none of the

    the Code or any comparable provision under state or foreign Tax laws as a
    result of transactions or events occurring, or accounting methods employed,
    prior to the Closing.
 
        (e) Except as set forth in Part 2.15(e) of the Company Disclosure
    Schedule, there is no agreement, plan, arrangement or other Contract
    covering any employee or independent contractor or former employee or
    independent contractor of any of the Acquired Corporations that, considered

    group" within the meaning of Section 414(m) of the Code. None of the
    Acquired Corporations has ever made a complete or partial withdrawal from a
    multi-employer plan, as such term is defined in Section 3(37) of ERISA,
    resulting in "withdrawal liability," as such term is defined in Section 4201
    of ERISA (without regard to subsequent reduction or waiver of such liability

    Schedule, no Plan provides death, medical or health benefits (whether or not

    (other than (i) benefit coverage mandated by applicable law, including
    coverage provided pursuant to Section 4980B of the Code, (ii) deferred
    compensation benefits accrued as liabilities on the Company Balance Sheet,
    and (iii) benefits the full cost of which are borne by current or former

    meaning of Section 4980B(g)(2) of the Code, the provisions of Section 4980B
    of the Code ("COBRA") have been complied with in all material respects. Part

    determination letter should be revoked.
 
        (k) Except as set forth in Part 2.16(k) of the Company Disclosure
    Schedule, neither the execution, delivery or performance of this Agreement,
    nor the consummation of the Merger or any of the other transactions
    contemplated by this Agreement, will result in any payment (including any
    bonus, golden parachute or severance payment) to any current or former
    employee or director of any of the Acquired Corporations (whether or not
    under any Plan), or materially increase the benefits payable under any Plan,
    or result in any acceleration of the time of payment or vesting of any such
    benefits.
 
        (l) Part 2.16(l) of the Company Disclosure Schedule contains a list of
    all salaried employees of each of the Acquired Corporations as of the date
    of this Agreement, and correctly reflects, in all material respects, their

        (o) Except as set forth in Part 2.16(o) of the Company Disclosure
    Schedule, each of the Acquired Corporations has good labor relations, and
    none of the Acquired Corporations has any knowledge of any facts indicating
    that (i) the consummation of the Merger or any of the other transactions
    contemplated by this Agreement will have a material adverse effect on the
    labor relations of any of the Acquired Corporations, or (ii) any of the
    employees of the Acquired Corporations intends to terminate his or her
    employment with the Acquired Corporation with which such employee is
    employed.
 
    2.17  ENVIRONMENTAL MATTERS.  Each of the Acquired Corporations is in
compliance in all material respects with all applicable Environmental Laws,
which compliance includes the possession by each of the
 
                                      A-17
<PAGE>
Acquired Corporations of all permits and other Governmental Authorizations
required under applicable Environmental Laws, and compliance with the terms and
conditions thereof. None of the Acquired Corporations has received any notice or
other communication (in writing or otherwise), whether from a Governmental Body,
citizens group, employee or otherwise, that alleges that any of the Acquired
Corporations is not in compliance with any Environmental Law, and, to the best
of the knowledge of the Company, there are no circumstances that may prevent or
interfere with the compliance by any of the Acquired Corporations with any
Environmental Law in the future. To the best of the knowledge of the Company, no
current or prior owner of any property leased or controlled by any of the
Acquired Corporations has received any notice or other communication (in writing
or otherwise), whether from a Government Body, citizens group, employee or
otherwise, that alleges that such current or prior owner or any of the Acquired
Corporations is not in compliance with any Environmental Law. To the best of the
knowledge of the Company, all property that is leased to, controlled by or used
by the Company, and all surface water, groundwater and soil associated with or
adjacent to such property is in clean and healthful condition and is free of any
material environmental contamination of any nature. (For purposes of this
Section 2.17 and Section 3.13: (i) "ENVIRONMENTAL LAW" means any federal, state,
local or foreign Legal Requirement relating to pollution or protection of human
health or the environment (including ambient air, surface water, ground water,
land surface or subsurface strata), including any law or regulation relating to
emissions, discharges, releases or threatened releases of Materials of
Environmental Concern, or otherwise relating to the manufacture, processing,
distribution, use, treatment, storage, disposal, transport or handling of
Materials of Environmental Concern; and (ii) "MATERIALS OF ENVIRONMENTAL
CONCERN" include chemicals, pollutants, contaminants, wastes, toxic substances,
petroleum and petroleum products and any other substance that is now or
hereafter regulated by any Environmental Law or that is otherwise a danger to
health, reproduction or the environment.)
 
    2.18  INSURANCE.  The Company has delivered to Parent a copy of each
insurance policy and each self insurance program relating to the business,
assets or operations of any of the Acquired Corporations. Each such insurance
policy is in full force and effect. Since June 3, 1996, none of the Acquired
Corporations has received any notice or other communication regarding any actual
or possible (a) cancellation or invalidation of any insurance policy, (b)
refusal of any coverage or rejection of any material claim under any insurance
policy, or (c) material adjustment in the amount of the premiums payable with
respect to any insurance policy. Except as set forth in Part 2.18 of the Company
Disclosure Schedule, there is no pending claim (including any workers'
compensation claim) under or based upon any insurance policy of any of the
Acquired Corporations; and, to the best of the knowledge of the Company, no
event has occurred, and no condition or circumstance exists, that might (with or
without notice or lapse of time) directly or indirectly give rise to or serve as
a basis for any such claim.
 
    2.19  TRANSACTIONS WITH AFFILIATES.  Except as set forth in the Company SEC
Documents, since the date of the Company's last proxy statement filed with the
SEC, no event has occurred that would be required to be reported by the Company
pursuant to Item 404 of Regulation S-K promulgated by the SEC. Part 2.19 of the
Company Disclosure Schedule identifies each person who is an "affiliate" (as
that term is used in Rule 145 promulgated under the Securities Act) of the
Company as of the date of this Agreement.
 
    2.20  LEGAL PROCEEDINGS; ORDERS.
 
        (a) Except as set forth in Part 2.20(a) of the Company Disclosure
    Schedule, there is no pending Legal Proceeding (including, to the best
    knowledge of the Company, any investigation), and no Person has overtly
    threatened to commence any Legal Proceeding: (i) that involves any of the
    Acquired Corporations or any of the assets owned or used by any of the
    Acquired Corporations, including, without limitation, any Acquired Company
    Proprietary Asset; or (ii) that challenges, or that may have the effect of
    preventing, delaying, making illegal or otherwise interfering with, the
    Merger or any of the other transactions contemplated by this Agreement. To
    the best of the knowledge of the Company, no event has occurred, and no
    claim, dispute or other condition or circumstance exists, that will, or
 
                                      A-18
<PAGE>
    that could reasonably be expected to, give rise to or serve as a basis for
    the commencement of any such Legal Proceeding. To the best of the knowledge
    of the Company, no event has occurred, and no claim, dispute or other
    condition or circumstance exists, that will, or that could reasonably be
    expected to, cause or provide a basis for a director, officer or other
    Representative of any of the Acquired Corporations to seek indemnification
    from, or commence a Legal Proceeding against or involving, any of the
    Acquired Corporations.
 
        (b) There is no order, writ, injunction, judgment or decree to which any
    of the Acquired Corporations, or any of the assets owned or used by any of
    the Acquired Corporations, is subject. To the best of the knowledge of the
    Company, no officer or other employee of any of the Acquired Corporations is
    subject to any order, writ, injunction, judgment or decree that prohibits
    such officer or other employee from engaging in or continuing any conduct,
    activity or practice relating to the business of any of the Acquired
    Corporations.
 
    2.21  AUTHORITY; INAPPLICABILITY OF ANTI-TAKEOVER STATUTES; BINDING NATURE
OF AGREEMENT.  The Company has the absolute and unrestricted right, corporate
power and authority to enter into and to perform its obligations under this
Agreement. The Board of Directors of the Company (at a meeting duly called and
held) has (a) unanimously determined that the Merger is advisable and fair and
in the best interests of the Company and its shareholders, (b) unanimously
approved the execution, delivery and performance of this Agreement by the
Company and has unanimously approved the Merger, (c) unanimously recommended the
adoption and approval of this Agreement and the Merger by the holders of Company
Common Stock and directed that this Agreement and the Merger be submitted for
consideration by the Company's shareholders at the Company Shareholders' Meeting
(as defined in Section 5.2), and (d) approved, and the stockholders of the
Company have adopted, an amendment to the Company's Articles of Incorporation
having the effect of causing the Company not to be subject to any state takeover
law or similar Legal Requirement that might otherwise apply to the Merger or any
of the other transactions contemplated by this Agreement except as set forth in
Part 2.21 of the Company Disclosure Schedule. This Agreement constitutes the
legal, valid and binding obligation of the Company, enforceable against the
Company in accordance with its terms, subject to (i) laws of general application
relating to bankruptcy, insolvency and the relief of debtors, and (ii) rules of
law governing specific performance, injunctive relief and other equitable
remedies.
 
    2.22  NO EXISTING DISCUSSIONS.  None of the Acquired Corporations, and no
Representative of any of the Acquired Corporations, is engaged, directly or
indirectly, in any discussions or negotiations with any other Person relating to
any Acquisition Proposal.
 
    2.23  ACCOUNTING MATTERS.  To the best of the knowledge of the Company,
neither the Company nor any of its affiliates has taken or agreed to, or plans
to, take any action that would prevent Parent from accounting for the Merger as
a "pooling of interests."
 
    2.24  VOTE REQUIRED.  The affirmative vote of the holders of a majority of
the shares of Company Common Stock outstanding on the record date for the
Company Shareholder Meeting (the "REQUIRED COMPANY SHAREHOLDER VOTE") is the
only vote of the holders of any class or series of the Company's capital stock
necessary to adopt and approve this Agreement, the Merger and the other
transactions contemplated by this Agreement.
 
    2.25  NON-CONTRAVENTION; CONSENTS.  Neither (i) the execution, delivery or
performance of this Agreement or any of the other agreements referred to in this
Agreement, nor (ii) the consummation of the
 
                                      A-19
<PAGE>
Merger or any of the other transactions contemplated by this Agreement, will
directly or indirectly (with or without notice or lapse of time):
 
        (a) contravene, conflict with or result in a violation of (i) any of the
    provisions of the articles of incorporation, bylaws or other charter or
    organizational documents of any of the Acquired Corporations, or (ii) any
    resolution adopted by the shareholders, the board of directors or any
    committee of the board of directors of any of the Acquired Corporations;
 
        (b) contravene, conflict with or result in a violation of, or give any
    Governmental Body or other Person the right to challenge the Merger or any

    injunction, judgment or decree to which any of the Acquired Corporations, or
    any of the assets owned or used by any of the Acquired Corporations, is
    subject;
 
        (c) contravene, conflict with or result in a violation of any of the
    terms or requirements of, or give any Governmental Body the right to revoke,

    Authorization that is held by any of the Acquired Corporations or that
    otherwise relates to the business of any of the Acquired Corporations or to
    any of the assets owned or used by any of the Acquired Corporations;
 
        (d) except as set forth in Part 2.25(d) of the Company Disclosure
    Schedule, contravene, conflict with or result in a violation or breach of,
    or result in a default under, any provision of any Acquired Corporation
    Contract that is or would constitute a Material Contract, or give any Person
    the right to (i) declare a default or exercise any remedy under any such
    Acquired Corporation Contract, (ii) a rebate, chargeback, penalty or change
    in delivery schedule under any such Acquired Corporation Contract, (iii)
    accelerate the maturity or performance of any such Acquired Corporation
    Contract, or (iv) cancel, terminate or modify any term of such Acquired
    Corporation Contract; or
 
        (e) result in the imposition or creation of any Encumbrance upon or with
    respect to any asset owned or used by any of the Acquired Corporations
    (except for minor liens that will not, in any case or in the aggregate,
    materially detract from the value of the assets subject thereto or
    materially impair the operations of any of the Acquired Corporations).
 
Except as may be required by the Exchange Act, the PBCL, the DGCL and the rules
of the National Association of Securities Dealers, Inc. ("NASD") (as they relate
to the S-4 Registration Statement and the Joint Proxy Statement/Prospectus, as
defined in Section 2.28(b)), none of the Acquired Corporations was, is or will
be required to make any filing with or give any notice to, or to obtain any
Consent from, any Person in connection with (x) the execution, delivery or
performance of this Agreement or any of the other agreements referred to in this
Agreement, or (y) the consummation of the Merger or any of the other
transactions contemplated by this Agreement.

    Documents: (i) complied as to form in all material respects with the
    published rules and regulations of the SEC applicable thereto; (ii) were

    Quarterly Report on Form 10-Q for the quarter ended June 30, 1998 is

    SHEET." All financial statements (including any related notes) contained in
    Company SEC Documents filed after the date hereof shall meet the conditions
    set forth in (i), (ii) and (iii) of this Section 3.3(b).

    required to be stated therein or necessary in order to make the statements
    therein, in the light of the circumstances under which they are made, not
    misleading. None of the information to be supplied by or on behalf of Parent
    for inclusion in the Joint Proxy Statement/Prospectus will, at the time the
    Joint Proxy Statement/Prospectus is mailed to the shareholders of Parent, at
    the time of the Parent Shareholders' Meeting or as of the Effective Time,

    by the SEC thereunder.
 
    3.5  ABSENCE OF CERTAIN CHANGES OR EVENTS.  Except as set forth in Part 3.5
of the Parent Disclosure Schedule between the date of the Parent Unaudited
Interim Balance Sheet and the date of this Agreement: (i) there has not been any
event that has had a Material Adverse Effect on Parent; (ii) Parent has not
declared, accrued, set aside or paid any dividend; and (iii) Parent has not
incurred any liabilities other than in the ordinary course of business and
consistent with past practices.
 
    3.6  AUTHORITY; BINDING NATURE OF AGREEMENT.  Parent and Merger Sub have the
absolute and unrestricted right, power and authority to perform their
obligations under this Agreement; and the execution, delivery and performance by
Parent and Merger Sub of this Agreement have been duly authorized by all
necessary action on the part of Parent and Merger Sub and their respective
boards of directors. This Agreement constitutes the legal, valid and binding
obligation of Parent and Merger Sub, enforceable against them in accordance with
its terms, subject to (i) laws of general application relating to bankruptcy,
insolvency and the relief of debtors, and (ii) rules of law governing specific
performance, injunctive relief and other equitable remedies.
 
    3.7  NON-CONTRAVENTION; CONSENTS.  Neither the execution and delivery of
this Agreement by Parent and Merger Sub nor the consummation by Parent and
Merger Sub of the Merger will (a) conflict with or result in any breach of any
provision of the certificate of incorporation or bylaws of Parent or the
articles of incorporation or bylaws of Merger Sub, or (b) result in a default by
Parent or Merger Sub under any Contract to which Parent or Merger Sub is a
party, except for any default which has not had and will not have a Material
Adverse Effect on Parent, or (c) result in a violation by Parent or Merger Sub
of any law, statute, rule, regulation, order, writ, injunction, judgment or
decree to which Parent or Merger Sub is subject, except for any violation which
has not had and will not have a Material Adverse Effect on Parent. Except as may
be required by the Securities Act, the Exchange Act, state securities or "blue
sky" laws, the PBCL, the DGCL and the rules of the NASD (as they relate to the
S-4 Registration Statement and the Joint Proxy Statement/Prospectus), Parent is
not and will not be required to make any filing with or give any notice to, or
to obtain any Consent from, any Person in connection with the execution and
delivery of this Agreement, or the consummation of the Merger.
 
    3.8  VOTE REQUIRED.  The only vote of Parent's stockholders required to
approve the issuance of Parent Common Stock in the Merger is the vote of a
majority of votes cast in person or by proxy as prescribed by rules of the NASD
(the "REQUIRED PARENT STOCKHOLDER VOTE").
 
    3.9  VALID ISSUANCE.  The Parent Common Stock to be issued in the Merger
will, when issued in accordance with the provisions of this Agreement, be duly
authorized, validly issued, fully paid and nonassessable.
 
    3.10  ACCOUNTING MATTERS.  To the best of the knowledge of Parent, Parent
has not taken and has not agreed, and does not plan, to take any action that
would prevent Parent from accounting for the Merger as a "pooling of interests."
 
    3.11  FAIRNESS OPINION.  Parent's Board of Directors has received the
written opinion of Hambrecht & Quist LLC, financial advisor to Parent, dated as
of the date of this Agreement, to the effect that
 
                                      A-23
<PAGE>
the Exchange Ratio is fair to Parent from a financial point of view. Parent has
furnished an accurate and complete copy of said written opinion to the Company.
 
    3.12  TAX MATTERS.
 
        (a) All Tax Returns required to be filed by or on behalf of the Parent
    and its Subsidiaries with any Governmental Body with respect to any taxable
    period ending on or before the Closing Date (the "PARENT RETURNS") (i) have
    been or will be filed on or before the applicable due date (including any
    extensions of such due date if properly obtained), and (ii) have been, or
    will be when filed, prepared in all material respects in compliance with all
    applicable Legal Requirements. All amounts shown on the Parent Returns to be
    due on or before the Closing Date have been or will be paid on or before the
    Closing Date.
 
        (b) The Parent financial statements in the Parent SEC Documents fully
    accrue all actual and contingent liabilities for Taxes with respect to all
    periods through the dates thereof in accordance with GAAP. Parent will
    establish, in the ordinary course of business and consistent with its past
    practices, reserves adequate for the payment of all Taxes for the period
    from the date of this Agreement through the Closing Date.
 
        (c) Since the Parent Return for the taxable period ended December 31,
    1992, no Parent Return has ever been examined or audited by any Governmental
    Body. No extension or waiver of the limitation period applicable to any of
    the Parent Returns has been granted (by Parent or any other Person), and no
    such extension or waiver has been requested from Parent or any of its
    Subsidiaries.
 
        (d) No claim or Legal Proceeding is pending or, to the best of the
    knowledge of the Parent, has been threatened against or with respect to
    Parent or any of its Subsidiaries in respect of any material Tax. There are
    no unsatisfied liabilities for material Taxes (including liabilities for
    interest, additions to tax and penalties thereon and related expenses) with
    respect to any notice of deficiency or similar document received by Parent
    or any of its Subsidiaries with respect to any material Tax (other than
    liabilities for Taxes asserted under any such notice of deficiency or
    similar document which are being contested in good faith by Parent or any of
    its Subsidiaries and with respect to which adequate reserves for payment
    have been established). There are no liens for material Taxes upon any of
    the assets of any of Parent or any of its Subsidiaries except liens for
    current Taxes not yet due and payable. Neither Parent nor any of its
    Subsidiaries has entered into or become bound by any agreement or consent
    pursuant to Section 341(f) of the Code. Neither Parent nor any of its
    Subsidiaries has been, and neither Parent nor any of its Subsidiaries will
    be, required to include any adjustment in taxable income for any tax period
    (or portion thereof) pursuant to Section 481 or 263A of the Code or any
    comparable provision under state or foreign Tax laws as a result of
    transactions or events occurring, or accounting methods employed, prior to
    the Closing.
 
        (e) There is no agreement, plan, arrangement or other Contract covering
    any employee or independent contractor or former employee or independent
    contractor of Parent or any of its Subsidiaries that, considered
    individually or considered collectively with any other such Contracts, will,
    or could reasonably be expected to, give rise directly or indirectly to the
    payment of any amount that would not be deductible pursuant to Section 280G
    or Section 162 of the Code. Neither Parent nor any of its Subsidiaries is,
    or has ever been, a party to or bound by any tax indemnity agreement, tax
    sharing agreement, tax allocation agreement or similar Contract.
 
    3.13  ENVIRONMENTAL MATTERS.  Except as set forth in Part 3.13 of the Parent
Disclosure Schedule, each of Parent and its Subsidiaries is in compliance in all
material respects with all applicable Environmental Laws, which compliance
includes the possession by each of Parent and its Subsidiaries of all permits
and other Governmental Authorizations required under applicable Environmental
Laws, and compliance with the terms and conditions thereof. Neither Parent nor
any of its Subsidiaries has received any notice or other communication (in
writing or otherwise), whether from a Governmental Body, citizens group,
 
                                      A-24
<PAGE>
employee or otherwise, that alleges that any of Parent or its Subsidiaries is
not in compliance with any Environmental Law, and, to the knowledge of Parent,
there are no circumstances that may prevent or interfere with the compliance by
Parent or any of its Subsidiaries with any Environmental Law in the future. To
the knowledge of the Parent, no current or prior owner of any property leased or
controlled by Parent or any of its Subsidiaries has received any notice or other
communication (in writing or otherwise), whether from a Government Body,
citizens group, employee or otherwise, that alleges that such current or prior
owner or Parent or any of its Subsidiaries is not in compliance with any
Environmental Law. To the knowledge of Parent, all property that is leased to,
controlled by or used by Parent, and all surface water, groundwater and soil
associated with or adjacent to such property is in clean and healthful condition
and is free of any material environmental contamination of any nature.
 
    3.14  SIGNIFICANT CUSTOMERS.  Part 3.14 of the Parent Disclosure Schedule
sets forth a complete and accurate list of all Parent's Significant Customers.
For purposes of this Agreement, "PARENT'S SIGNIFICANT CUSTOMERS" are the twenty
(20) customers of the Parent that have effected the most purchases, in dollar
terms, and accounted for the most revenues, in dollar terms, during the fiscal
year ended December 31, 1997. None of the Parent's Significant Customers has
canceled, returned or substantially reduced or, to the knowledge of the Parent,
is currently attempting or threatening to cancel, return or substantially
reduce, any purchases from, orders to or services provided by the Parent. Parent
has not received any material customer complaints concerning its products and/or
services.
 
    3.15  YEAR 2000 LIABILITIES.  Neither Parent nor any of its Subsidiaries has
any accrued, contingent or other liabilities of any nature, either matured or
unmatured, including, without limitation, any liabilities relating to costs
associated with insuring that all software (and related Parent Proprietary
Assets) that is sold, licensed or transferred by Parent or any of its
Subsidiaries to any Person, computer systems, any software utilized by the
Parent or other components of the Parent's information technology infrastructure
are Year 2000 Compliant (whether or not required to be reflected in financial
statements in accordance with GAAP, and whether due or to become due), except
for: (a) liabilities identified as such in the "liabilities" column of the
Parent Unaudited Interim Balance Sheet as of June 30, 1998 included in the
Parent's Quarterly Report on Form 10-Q for the quarter ended June 30, 1998; and
(b) normal and recurring liabilities that have been incurred by Parent since the
date of the Parent Unaudited Interim Balance Sheet in the ordinary course of
business and consistent with past practices.

                                      A-28
<PAGE>
    not prohibit the Company from furnishing nonpublic information regarding the
    Acquired Corporations to, or entering into discussions with, any Person in
    response to a Superior Offer submitted by such Person (and not withdrawn) if
    (1) neither the Company nor any Representative of any of the Acquired
    Corporations shall have violated any of the restrictions set forth in this
    Section 4.3, (2) the Board of Directors of the Company concludes in good
    faith, based upon the advice of its outside legal counsel, that such action
    is required in order for the Board of Directors of the Company to comply
    with its fiduciary obligations to the Company's shareholders under
    applicable law, (3) prior to furnishing any such nonpublic information to,
    or entering into discussions with, such Person, the Company gives Parent
    written notice of the identity of such Person and of the Company's intention
    to furnish nonpublic information to, or enter into discussions with, such
    Person, and the Company receives from such Person an executed
    confidentiality agreement containing customary limitations on the use and
    disclosure of all nonpublic written and oral information furnished to such
    Person by or on behalf of the Company, and (4) prior to furnishing any such
    nonpublic information to such Person, the Company furnishes such nonpublic
    information to Parent (to the extent such nonpublic information has not been
    previously furnished by the Company to Parent). Without limiting the
    generality of the foregoing, the Company acknowledges and agrees that any
    violation of any of the restrictions set forth in the preceding sentence by
    any Representative of any of the Acquired Corporations, whether or not such
    Representative is purporting to act on behalf of any of the Acquired
    Corporations, shall be deemed to constitute a breach of this Section 4.3 by
    the Company. In addition to the foregoing, the Company shall (i) provide
    Parent with at least twenty-four (24) hours prior notice of any meeting of
    the Company's Board of Directors at which the Company's Board of Directors
    is reasonably expected to consider a Superior Offer and (ii) not recommend a
    Superior Offer to its shareholders for a period of not less than the greater
    of two (2) business days or forty-eight (48) hours after Parent's receipt of
    a copy of such Superior Offer (pursuant to Section 4.3(b) below).
 
        (b) The Company shall promptly advise Parent orally and in writing of
    any Acquisition Proposal (including the identity of the Person making or
    submitting such Acquisition Proposal and the terms thereof) that is made or
    submitted by any Person during the Pre-Closing Period. The Company shall
    keep Parent fully informed with respect to the status of any such
    Acquisition Proposal and any modification or proposed modification thereto.
 
        (c) The Company shall immediately cease and cause to be terminated any
    existing discussions with any Person that relate to any Acquisition
    Proposal.

    Registration Statement, together with the Joint Proxy Statement/Prospectus
    and any other documents required by the Securities Act, the Exchange Act or
    any other Federal, foreign or Blue Sky or related laws in connection with
    the Merger and the transactions contemplated by this Agreement ("OTHER
    FILINGS"). Each of Parent and the Company will notify the other promptly
    upon the receipt of any comments from the SEC or its staff or any other
    government officials and of any request by the SEC or its staff or any other
    government officials for amendments or supplements to the S-4 Registration
    Statement, the Joint Proxy Statement/Prospectus or any Other Filings or for
    additional information and will supply the other with copies of all
    correspondence between such party or any of its representatives, on the one
    hand, and the SEC, or its staff or any other government officials, on the
    other hand, with respect to the S-4 Registration Statement, the Joint Proxy
    Statement/Prospectus, any Other Filings or the Merger. Each of Parent and
    the Company shall use all reasonable efforts to cause the S-4 Registration
    Statement (including the Joint Proxy Statement/Prospectus) and any Other
    Filings to comply with the rules and regulations promulgated by the SEC, to
    respond promptly to any comments of the SEC or its staff and to have the
 
                                      A-29
<PAGE>
    S-4 Registration Statement declared effective under the Securities Act as
    promptly as practicable after it is filed with the SEC. Parent will use all
    reasonable efforts to cause the Joint Proxy Statement/ Prospectus to be
    mailed to Parent's stockholders and the Company will use all reasonable
    efforts to cause the Joint Proxy Statement/Prospectus to be mailed to the
    Company's shareholders, as promptly as practicable after the Form S-4
    Registration Statement is declared effective under the Securities Act. The
    Company shall promptly furnish to Parent all information concerning the
    Acquired Corporations and the Company's shareholders that may be required or
    reasonably requested in connection with any action contemplated by this
    Section 5.1. If any event relating to any of the Acquired Corporations
    occurs, or if the Company becomes aware of any information, that should be
    set forth in an amendment or supplement to the S-4 Registration Statement or
    the Joint Proxy Statement/Prospectus, then the Company shall promptly inform
    Parent thereof and shall cooperate with Parent in filing such amendment or
    supplement with the SEC and, if appropriate, in mailing such amendment or
    supplement to the shareholders of the Company and the stockholders of
    Parent.
 
        (b) Prior to the Effective Time, Parent shall use reasonable efforts to
    obtain all regulatory approvals needed to ensure that the Parent Common
    Stock to be issued in the Merger will be registered or qualified under the
    securities law of every jurisdiction of the United States in which any
    registered holder of Company Common Stock has an address of record on the
    record date for determining the shareholders entitled to notice of and to
    vote at the Company Shareholders' Meeting; PROVIDED, HOWEVER, that Parent
    shall not be required (i) to qualify to do business as a foreign corporation
    in any jurisdiction in which it is not now qualified or (ii) to file a
    general consent to service of process in any jurisdiction.
 
    5.2  COMPANY SHAREHOLDERS' MEETING.
 
        (a) The Company shall take all action necessary under all applicable
    Legal Requirements to call, give notice of, convene and hold a meeting of
    the holders of Company Common Stock (the "COMPANY SHAREHOLDERS' MEETING") to
    consider, act upon and vote upon the adoption of this Agreement and approval
    of the Merger. The Company Shareholders' Meeting will be held as promptly as
    practicable and in any event within forty-five (45) days after the S-4
    Registration Statement is declared effective under the Securities Act;
    PROVIDED, HOWEVER, that notwithstanding anything to the contrary contained
    in this Agreement, the Company may adjourn or postpone the Company
    Shareholders' Meeting to the extent necessary to ensure that any necessary
    supplement or amendment to the Joint Proxy Statement/ Prospectus is provided
    to the Company's shareholders in advance of a vote on the Merger and this
    Agreement or, if as of the time for which Company Shareholders' Meeting is
    originally scheduled (as set forth in the Joint Proxy Statement/Prospectus)
    there are insufficient shares of Company Common Stock represented (either in
    person or by proxy) to constitute a quorum necessary to conduct the business
    of the Company's Shareholders' Meeting. The Company shall ensure that the
    Company Shareholders' Meeting is called, noticed, convened, held and
    conducted, and that all proxies solicited in connection with the Company
    Shareholders' Meeting are solicited, in compliance with all applicable Legal
    Requirements. The Company's obligation to call, give notice of, convene and
    hold the Company Shareholders' Meeting in accordance with this Section
    5.2(a) shall not be limited or otherwise affected by the commencement,
    disclosure, announcement or submission to the Company of any Acquisition
    Proposal, or by any withdrawal, amendment or modification of the
    recommendation of the Board of Directors of the Company with respect to the
    Merger.
 
        (b) Subject to Section 5.2(c): (i) the Board of Directors of the Company
    shall unanimously recommend that the Company's shareholders vote in favor of
    and adopt and approve this Agreement and the Merger at the Company
    Shareholders' Meeting; (ii) the Joint Proxy Statement/Prospectus shall
    include a statement to the effect that the Board of Directors of the Company
    has unanimously recommended that the Company's shareholders vote in favor of
    and adopt and approve this Agreement and the Merger at the Company
    Shareholders' Meeting; and (iii) neither the Board of Directors of the
    Company nor any committee thereof shall withdraw, amend or modify, or
    propose or resolve to
 
                                      A-30
<PAGE>
withdraw, amend or modify, in a manner adverse to Parent, the unanimous
recommendation of the Board of Directors of the Company that the Company's
shareholders vote in favor of and adopt and approve this Agreement and the
Merger. For purposes of this Agreement, said recommendation of the Board of
Directors shall be deemed to have been modified in a manner adverse to Parent if
said recommendation shall no longer be unanimous.
 
        (c) Nothing in Section 5.2(b) shall prevent the Board of Directors of
    the Company from withdrawing, amending or modifying its unanimous
    recommendation in favor of the Merger if (i) a Superior Offer is made to the
    Company and is not withdrawn, (ii) neither the Company nor any of its
    Representatives shall have violated any of the restrictions set forth in
    Section 4.3, and (iii) the Board of Directors of the Company concludes in
    good faith, based upon the advice of its outside counsel, that, in light of
    such Superior Offer, the withdrawal, amendment or modification of such
    recommendation is required in order for the Board of Directors of the
    Company to comply with its fiduciary obligations to the Company's
    shareholders under applicable law. Nothing contained in this Section 5.2
    shall limit the Company's obligation to hold and convene the Company
    Shareholders' Meeting (regardless of whether the unanimous recommendation of
    the Board of Directors of the Company shall have been withdrawn, amended or
    modified).
 
    5.3  PARENT STOCKHOLDERS' MEETING.
 
        (a) Parent shall take all action necessary to call, give notice of,
    convene and hold a meeting of the holders of Parent Common Stock to consider
    and vote upon the issuance of Parent Common Stock in the Merger (the "PARENT
    STOCKHOLDERS' MEETING"). The Parent Stockholders' Meeting will be held as
    promptly as practicable and in any event within forty-five (45) days after
    the S-4 Registration Statement is declared effective under the Securities
    Act; PROVIDED, HOWEVER, that notwithstanding anything to the contrary
    contained in this Agreement, Parent may adjourn or postpone the Parent
    Stockholders' Meeting to the extent necessary to ensure that any necessary
    supplement or amendment to the Joint Proxy Statement/Prospectus is provided
    to Parent's stockholders in advance of a vote on the issuance of Parent
    Common Stock in the Merger or, if as of the time for which the Parent
    Stockholders' Meeting is originally scheduled (as set forth in the Joint
    Proxy Statement/Prospectus) there are insufficient shares of Parent Common
    Stock represented (either in person or by proxy) to constitute a quorum
    necessary to conduct the business of the Parent's Stockholders' Meeting.
 
        (b) (i) The board of directors of Parent shall unanimously recommend
    that Parent's stockholders vote in favor of the issuance of Parent Common
    Stock in the Merger; (ii) the Joint Proxy Statement/ Prospectus shall
    include a statement to the effect that the board of directors of Parent has
    unanimously recommended that Parent's stockholders vote in favor of the
    issuance of Parent Common Stock in the Merger; and (iii) neither the board
    of directors of Parent nor any committee thereof shall withdraw, amend or
    modify, or propose or resolve to withdraw, amend or modify, in a manner
    adverse to the Company, the unanimous recommendation of the board of
    directors of Parent that Parent's stockholders vote in favor of the issuance
    of Parent Common Stock in the Merger. For purposes of this Agreement, said
    recommendation of Parent's board of directors shall be deemed to have been
    modified in a manner adverse to the Company if said recommendation shall no
    longer be unanimous.
 
    5.4  REGULATORY APPROVALS.  The Company and Parent shall use all reasonable
efforts to file, as soon as practicable after the date of this Agreement, all
notices, reports and other documents required to be filed with any Governmental
Body with respect to the Merger and the other transactions contemplated by this
Agreement, and to submit promptly any additional information requested by any
such Governmental Body. The Company and Parent shall respond as promptly as
practicable to any inquiries or requests received from any state attorney
general or other Governmental Body in connection with antitrust or related
matters. Each of the Company and Parent shall (1) give the other party prompt
notice of the commencement of any Legal Proceeding by or before any Governmental
Body with respect to the Merger or any of the other transactions contemplated by
this Agreement, (2) keep the other party informed as to
 
                                      A-31
<PAGE>
the status of any such Legal Proceeding, and (3) promptly inform the other party
of any communication to or from the Federal Trade Commission, the Department of
Justice or any other Governmental Body regarding the Merger. The Company and
Parent will consult and cooperate with one another, and will consider in good
faith the views of one another, in connection with any analysis, appearance,
presentation, memorandum, brief, argument, opinion or proposal made or submitted
in connection with any Legal Proceeding under or any other federal or state
antitrust or fair trade law. In addition, except as may be prohibited by any
Governmental Body or by any Legal Requirement, in connection with any Legal
Proceeding under or any other federal or state antitrust or fair trade law or
any other similar Legal Proceeding, each of the Company and Parent agrees to
permit authorized Representatives of the other party to be present at each
meeting or conference relating to any such Legal Proceeding and to have access
to and be consulted in connection with any document, opinion or proposal made or
submitted to any Governmental Body in connection with any such Legal Proceeding.

        (a) Subject to Section 5.5(b), at the Effective Time, all rights with
    respect to Company Common Stock under each Company Option then outstanding
    shall be converted into and become rights with respect to Parent Common
    Stock, and Parent shall assume each such Company Option in accordance with
    the requirements of Section 424(a) of the Code (as in effect as of the date
    of this Agreement) and the terms of the stock option plan under which it was
    issued and the stock option agreement by which it is evidenced. From and
    after the Effective Time, (i) each Company Option assumed by Parent may be

    Company Option immediately prior to the Effective Time multiplied by the
    Exchange Ratio, rounding down to the nearest whole share (with cash, less
    the applicable exercise price, being payable for any fraction of a share),
    (iii) the per share exercise price under each such Company Option shall be
    adjusted by dividing the per share exercise price under such Company Option
    by the Exchange Ratio and rounding up to the nearest cent and (iv) any
    restriction on the exercise of any such Company Option shall continue in
    full force and effect and the term, exercisability, vesting schedule and
    other provisions of such Company Option shall otherwise remain unchanged;
    PROVIDED, HOWEVER, that each Company Option assumed by Parent in accordance
    with this Section 5.5(a) shall, in accordance with its terms, be subject to
    further adjustment as appropriate to reflect any stock split, stock
    dividend, reverse stock split, reclassification, recapitalization or other
    similar transaction subsequent to the Effective Time.
 
        (b) Notwithstanding anything to the contrary contained in this Section
    5.5, in lieu of assuming outstanding Company Options in accordance with
    Section 5.5(a), Parent may, at its election, cause such outstanding Company
    Options to be replaced by issuing equivalent replacement stock options in
    substitution therefor that are substantially the same.
 
        (c) The Company shall take all action that may be necessary (under the
    plans pursuant to which Company Options are outstanding and otherwise) to
    effectuate the provisions of this Section 5.5 and to ensure that, from and

    respect thereto other than those specifically provided in this Section 5.5.

Common Stock under Company Warrants that are then outstanding shall be converted
into and become rights with respect to Parent Common Stock, and Parent shall

date hereof) of such Company Warrants. From and after the Effective Time, (a)
each Company Warrant assumed by Parent may be exercised solely for shares of
Parent Common Stock, (b) the
 
                                      A-32
<PAGE>
number of shares of Parent Common Stock subject to each Company Warrant shall be
equal to the number of shares of Company Common Stock subject to such Company
Warrant immediately prior to the Effective Time multiplied by the Exchange
Ratio, rounding down to the nearest whole share (with cash, less the applicable
exercise price, being payable for any fraction of a share), (c) the per share
exercise price under each such Company Warrant shall be adjusted by dividing the
per share exercise price under such Company Warrant by the Exchange Ratio and
rounding up to the nearest cent and (d) any restriction on the exercise of any
Company Warrant shall continue in full force and effect and the term,
exercisability, schedule and other provisions of such Company Warrant shall
otherwise remain unchanged; PROVIDED, HOWEVER, that such Company Warrant shall,
in accordance with its terms, be subject to further adjustment as appropriate to
reflect any stock split, stock dividend, recapitalization or other similar
transaction subsequent to the Effective Time. The Company shall take all action
that may be necessary (under the Company Warrants and otherwise) to effectuate
the provisions of this Section 5.7 and to ensure that, from and after the
Effective Time, holders of Company Warrants have no rights with respect thereto
other than those specifically provided herein.

    agreements between the Company and said officers and directors (as in effect
    as of the date of this Agreement), shall survive the Merger and shall be
    observed by Parent and the Surviving Corporation for a period of not less
    than six (6) years from the Effective Time.
 
        (b) From the Effective Time until the third anniversary of the date on

    Time, the lesser of (i) the existing amount of coverage of the existing
    policy of directors' and officers' liability insurance maintained by the
    Company as of the date of this Agreement (the "EXISTING POLICY") and (ii)
    the amount of coverage purchased by 150% of the amount of the last annual
    premium paid by the Company prior to the date of this Agreement for the
    Existing Policy; PROVIDED, HOWEVER, that the Surviving Corporation may
    substitute for the Existing Policy a policy or policies of comparable
    coverage.
 
    5.9  POOLING OF INTERESTS; TAX FREE REORGANIZATION.  Each of the Company and
Parent agrees (a) not to take any action during the Pre-Closing Period that
would adversely affect the ability of Parent to account for the Merger as a
"pooling of interests," (b) to use all reasonable efforts to attempt to ensure
that none of its "affiliates" (as that term is used in Rule 145 promulgated
under the Securities Act) takes any action that could adversely affect the
ability of Parent to account for the Merger as a "pooling of interests" and (c)
not to take any action either prior to or after the Effective Time that could
reasonably be expected to cause the Merger to fail to qualify as a
"reorganization" under Section 368(a) of the Code. The Company agrees to provide
KPMG Peat Marwick LLP and Grant Thornton LLP such letters as may be reasonably
requested by either of them with respect to the letters referred to in Sections
6.6(b) and 6.6(c).

    shall have been breached in any material respect; PROVIDED, HOWEVER, that if
    an inaccuracy in the Company's representations and warranties or a breach of

Ladies and Gentlemen:
 
   
    Integrated Systems Consulting Group, Inc. (the "Company") proposes to enter
into an Agreement and Plan of Merger and Reorganization (the "Agreement") with
First Consulting Group, Inc. ("Parent") and Foxtrot Acquisition Sub, Inc., a
wholly owned subsidiary of Parent ("Merger Sub"). Pursuant to the Agreement, at
the Effective Time (as defined in the Agreement), Merger Sub shall be merged
with and into the Company (the "Merger") and each issued and outstanding share
of Common Stock, par value $.005 per share ("Company Common Stock"), of the
Company (other than Dissenting Shares (as defined in the Agreement) and shares
held by the Company, Parent or any of their respective subsidiaries) will be
converted solely into the right to receive 0.77 of one share of Common Stock,
par value $.001 per share ("Parent Common Stock"), of Parent (the "Exchange
Ratio").
    
 
    You have requested our opinion as to the fairness, from a financial point of
view, of the Exchange Ratio to the holders of Company Common Stock (other than
Parent and its affiliates).
 
    Robert W. Baird & Co. Incorporated ("Baird"), as part of its investment
banking business, is engaged in the evaluation of businesses and their
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements, and valuations for estate, corporate
and other purposes.
 
    In conducting our investigation and analysis and in arriving at our opinion
herein, we have reviewed such information and taken into account such financial
and economic factors as we have deemed relevant under the circumstances. In that
connection, we have, among other things: (i) reviewed certain internal
information, primarily financial in nature, including projections, concerning
the business and operations of the Company and Parent furnished to us for
purposes of our analysis, as well as publicly available information including
but not limited to the Company's and the Parent's recent filings with the
Securities and Exchange Commission and equity analyst research reports prepared
by various investment banking firms including Baird; (ii) reviewed the Agreement
in the form presented to the Company's Board of Directors; (iii) compared the
historical market prices and trading activity of the Company Common Stock and
Parent Common Stock with those of certain other publicly traded companies we
deemed relevant; (iv) compared the financial position and operating results of
the Company and Parent with those of other publicly traded companies we deemed
relevant; (v) compared the proposed financial terms of the Merger with the
financial terms of certain other business combinations we deemed relevant; and
(vi) reviewed certain potential pro forma effects of the Merger. We have held
discussions with members of the Company's and Parent's respective senior
managements concerning the Company's and Parent's historical and current
financial condition and operating results, as well as the future prospects of
the Company and Parent, respectively. As a part of our engagement we were
requested to and did solicit third party indications of interest in acquiring
the Company. We have also considered such other information,

financial studies, analysis and investigations and financial, economic and
market criteria which we deemed relevant for the preparation of this opinion.
 
    In arriving at our opinion, we have assumed and relied upon the accuracy and
completeness of all of the financial and other information that was publicly
available or provided us by or on behalf of the Company and the Parent, and have
not been engaged to independently verify any such information. We have assumed,
with your consent, (i) that all material assets and liabilities (contingent or
otherwise, known or unknown) of the Company and the Parent are as set forth in
their respective financial statements, (ii) the Merger will be accounted for
under the pooling-of-interests method and (iii) the Merger will be consummated
in accordance with the terms of the Agreement, without any amendment thereto and
without waiver by the Company or Parent of any of the conditions to their
respective obligations thereunder. At your direction, we have assumed that no
cost savings or operating synergies will result from the Merger, and have
excluded transaction costs from our financial analysis. We have also assumed
that the financial forecasts examined by us were reasonably prepared on bases
reflecting the best available estimates and good faith judgments of the
Company's and Parent's respective senior managements as to future performance of
the Company and Parent, respectively. In conducting our review, we have not
undertaken nor obtained an independent evaluation or appraisal of any of the
assets or liabilities (contingent or otherwise) of the Company and Parent nor
have we made a physical inspection of the properties or facilities of the
Company or Parent. Our opinion necessarily is based upon economic, monetary and
market conditions as they exist and can be evaluated on the date hereof, and
does not predict or take into account any changes which may occur, or
information which may become available, after the date hereof. Furthermore, we
express no opinion as to the price or trading range at which any of the
Company's or Parent's securities (including the Company Common Stock and Parent
Common Stock) will trade following the date hereof.
 
    Our opinion has been prepared at the request and for the information of the
Board of Directors of the Company, and shall not be used for any other purpose
or disclosed to any other party without the prior written consent of Baird;
provided, however, that this letter may be reproduced in full in the Proxy
Statement/Prospectus to be provided to the Company's stockholders in connection
with the Merger. This opinion does not address the relative merits of the Merger
and any other potential transactions or business strategies considered by the
Company's Board of Directors, and does not constitute a recommendation to any
shareholder of the Company as to how any such shareholder should vote with
respect to the Merger. Baird will receive a fee for rendering this opinion. In
the past, Baird has performed investment banking services for the Company,
including acting as co-manager in the Company's 1996 public offering of the
Company's Common Stock. Additionally, in the past Baird has performed investment
banking services for Safeguard Scientifics, Inc., an affiliate of the Company,
as well as for certain other affiliates of Safeguard Scientifics, Inc., for
which Baird has received customary compensation.
 
    In the ordinary course of our business, we may from time to time trade the
securities of the Company or Parent for our own account or the accounts of our
customers and, accordingly, may at any time hold long or short positions in such
securities.
 
    Based upon and subject to the foregoing, we are of the opinion that, as of
the date hereof, the Exchange Ratio is fair, from a financial point of view, to
the holders of Company Common Stock (other than Parent and its affiliates).
 
Very truly yours,

Gentlemen:
 
   
    You have requested our opinion as to the fairness from a financial point of
view to First Consulting Group, Inc. ("First Consulting" or the "Company") of
the Exchange Ratio (as defined below) in connection with the proposed merger of
a wholly owned subsidiary of First Consulting with and into Integrated Systems
Consulting Group, Inc. ("ISCG") (the "Proposed Transaction") under the terms of
the Agreement and Plan of Merger and Reorganization, dated as of September 9,
1998, among ISCG, First Consulting and Foxtrot Acquisition Sub, Inc. and the
related Exhibits and Schedules thereto (the "Agreement"). The Agreement
provides, among other things, that each issued and outstanding share of Common
Stock of ISCG will be converted, upon consummation of the Proposed Transaction,
into 0.77 shares of First Consulting Common Stock (the "Exchange Ratio). For
purposes of this opinion, we have assumed that the Proposed Transaction will
qualify as a tax-free reorganization under the United States Internal Revenue
Code and that the Proposed Transaction will be accounted for as a pooling-of-
interests.
    
 
    Hambrecht & Quist LLC ("Hambrecht & Quist"), as part of its investment
banking services, is regularly engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, strategic transactions,
corporate restructurings, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements and valuations for corporate
and other purposes. We have acted as a financial advisor to the Board of
Directors of First Consulting in connection with the Proposed Transaction, and
we will receive a fee for our services, which include the rendering of this
opinion.
 
    In the past, we have provided investment banking and other financial
advisory services to First Consulting and have received fees for rendering these
services. In particular, Hambrecht & Quist acted as lead underwriter of the
Company's initial public offering on February 13, 1998, and received a fee for

services. In the ordinary course of business, Hambrecht & Quist acts as a market
maker and broker in the publicly traded securities of First Consulting and
receives customary compensation in connection therewith, and also provides
research coverage for First Consulting. In the ordinary course of business,
Hambrecht & Quist actively trades in the equity and derivative securities of
First Consulting for its own account and for the accounts of its customers and,
accordingly, may at any time hold a long or short position in such securities.
Hambrecht & Quist may in the future provide additional investment banking or
other financial advisory services to First Consulting.
 
    In connection with our review of the Proposed Transaction, and in arriving
at our opinion, we have, among other things:
 
        (i) reviewed the publicly available consolidated financial statements
    First Consulting for recent years and interim periods to date and certain
    other relevant financial and operating data of First Consulting made
    available to us from published sources and from the internal records of
    First Consulting;
 
        (ii) reviewed certain internal financial and operating information,
    including certain projections, relating to First Consulting prepared by the
    management of First Consulting;
 
       (iii) discussed the business, financial condition and prospects of First
    Consulting with certain of its officers;
 
        (iv) reviewed the publicly available consolidated financial statements
    of ISCG for recent years and interim periods to date and certain other
    relevant financial and operating data of ISCG made available to us from
    published sources and from the internal records of ISCG;
 
        (v) reviewed certain internal financial and operating information,
    including certain projections, relating to ISCG prepared by the management
    of ISCG;
 
        (vi) discussed the business, financial condition and prospects of ISCG
    with certain of its officers;
 
   
       (vii) reviewed the recent reported prices and trading activity for the
    Common Stocks of First Consulting and ISCG and compared such information and
    certain financial information for First Consulting and ISCG with similar
    information for certain other companies engaged in businesses we consider
    comparable;
    
 
      (viii) reviewed the financial terms, to the extent publicly available, of
    certain comparable merger and acquisition transactions;
 
        (ix) reviewed the Agreement; and
 
        (x) performed such other analyses and examinations and considered such
    other information, financial studies, analyses and investigations and
    financial, economic and market data as we deemed relevant.
 
    In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning First Consulting or ISCG
considered in connection with our review of the Proposed Transaction, and we
have not assumed any responsibility for independent verification of such
information. We have not undertaken any independent valuation or appraisal of
any of the assets or liabilities of First Consulting or ISCG; nor have we
conducted a physical inspection of the properties and facilities of either
company. With respect to the financial forecasts and projections made available
to us and used in our analysis, we have assumed that they reflect the best
currently available estimates and judgments of the expected future financial
performance of First Consulting and ISCG. For purposes of this

Opinion, we have assumed that neither First Consulting nor ISCG is a party to
any pending transactions, including external financings, recapitalizations or
material merger discussions, other than the Proposed Transaction and those
activities undertaken in the ordinary course of conducting their respective
businesses. Our opinion is necessarily based upon market, economic, financial
and other conditions as they exist and can be evaluated as of the date of this
letter and any change in such conditions would require a reevaluation of this
opinion. Hambrecht & Quist expresses no opinion as to the price at which First

representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).

in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and

provision or part thereof under any other circumstances or in any other

    This proxy shall be binding upon the heirs, estate, executors, personal
representatives, successors and assigns of the undersigned (including any
transferee of any of the Shares).
 
    If any provision of this proxy or any part of any such provision is held
under any circumstances to be invalid or unenforceable in any jurisdiction, then
(a) such provision or part thereof shall, with respect to such circumstances and
in such jurisdiction, be deemed amended to conform to applicable laws so as to
be valid and enforceable to the fullest possible extent, (b) the invalidity or
unenforceability of such provision or part thereof under such circumstances and
in such jurisdiction shall not affect the validity or enforceability of such
provision or part thereof under any other circumstances or in any other
jurisdiction, and (c) the invalidity or unenforceability of such provision or
part thereof shall not affect the validity or enforceability of the remainder of
such provision or the validity or enforceability of any other provision of this
proxy. Each provision of this proxy is separable from every other provision of

                          COMPANY AFFILIATE AGREEMENT
 
    THIS COMPANY AFFILIATE AGREEMENT (this "AGREEMENT") is dated as of September
9, 1998, by and between FIRST CONSULTING GROUP, INC., a Delaware corporation
("PARENT"), INTEGRATED SYSTEMS CONSULTING GROUP, INC., a Pennsylvania
corporation ("COMPANY"), and the undersigned affiliate ("AFFILIATE").
 
                                    RECITALS
 
    WHEREAS, Affiliate is a stockholder of Company.
 
   
    WHEREAS, Parent, Foxtrot Acquisition Sub, Inc., a Delaware corporation and a
wholly-owned subsidiary of Parent ("MERGER SUB"), and Company have entered into
an Agreement and Plan of Merger and Reorganization dated as of September 9, 1998
(the "MERGER AGREEMENT"), providing for the merger of Merger Sub with and into
Company (the "MERGER"). The Merger Agreement contemplates that, upon
consummation of the Merger, (i) the holders of the Common Stock of Company
("COMPANY COMMON STOCK") will receive shares of Common Stock of Parent ("PARENT
COMMON STOCK") in exchange for their shares of Company Common Stock and (ii)
Company will become a wholly-owned subsidiary of Parent. It is accordingly
contemplated that Affiliate will receive shares of Parent Common Stock in the
Merger.
    
 
    WHEREAS, Affiliate understands that the Parent Common Stock being issued in
the Merger will be issued pursuant to a registration statement on Form S-4 and
that Affiliate may be deemed to be an "affiliate" of Company, as the term
"affiliate" is used (i) for purposes of paragraphs (c) and (d) of Rule 145
("RULE 145") of the General Rules and Regulations of the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"SECURITIES ACT"), and (ii) in the SEC's Accounting Series Releases 130 and 135,
and, as such, Affiliate may only transfer, sell or dispose of such Parent Common
Stock in accordance with this Affiliate Agreement and Rule 145.
 
    WHEREAS, it is a condition to the consummation of the Merger pursuant to the
Merger Agreement that the independent accounting firms that audit the annual
financial statements of Parent and Company will have delivered the written
concurrences with the conclusions of management of Parent and Company to the
effect that the Merger will be accounted for as a pooling of interests under
Accounting Principles Board Opinion No. 16.
 
                                   AGREEMENT
 
    NOW, THEREFORE, in order to induce Parent and Company to consummate the
transactions contemplated by the Merger Agreement, and for other valuable
consideration (the receipt and sufficiency of which are hereby acknowledged by
Affiliate), Affiliate hereby covenants and agrees as follows:
 
    1.  REPRESENTATIONS AND WARRANTIES.  Affiliate represents and warrants to
Parent as follows:
 
        (a) Affiliate is the holder and "beneficial owner" (as defined in Rule
    13d-3 under the Securities Exchange Act of 1934, as amended) of the number
    of shares of Company Common Stock set forth under Affiliate's signature
    below (the "COMPANY SHARES"), and Affiliate has good and valid title to
    Company Shares, free and clear of any liens, pledges, security interests,
    adverse claims, equities, options, proxies, charges, encumbrances or
    restrictions of any nature.
 
        (b) Affiliate has carefully read this Agreement, and has discussed with
    Affiliate's own independent counsel to the extent Affiliate felt necessary
    the limitations imposed on Affiliate's ability to sell, transfer or
    otherwise dispose of the shares of Parent Common Stock that Affiliate is to
    receive in the Merger (the "PARENT SHARES"). Affiliate fully understands the
    limitations this Agreement places upon Affiliate's ability to sell, transfer
    or otherwise dispose of the Parent Shares.
 
                                     D-1-1
<PAGE>
        (c) Affiliate understands that the representations, warranties and
    covenants set forth herein will be relied upon by Parent, Company, and their
    respective affiliates, counsel and accounting firms for purposes of
    determining Parent's eligibility to account for the Merger as a "pooling of
    interests," and that substantial losses and damages may be incurred by these
    persons if Affiliate's representations, warranties or covenants are
    breached.
 
    2.  PROHIBITION AGAINST TRANSFER.  In addition to the restrictions set forth
elsewhere herein, Affiliate agrees that Affiliate shall not effect any sale,
transfer or other disposition of the Parent Shares unless:
 
        (a) such sale, transfer or other disposition is made in conformity with
    the volume and other requirements of Rule 145 under the Securities Act, as
    evidenced by a broker's letter and a representation letter executed by
    Affiliate (reasonably satisfactory in form and content to Parent), each
    stating that such requirements have been met;
 
        (b) counsel reasonably satisfactory to Parent shall have advised Parent
    in a written opinion letter (reasonably satisfactory in form and content to
    Parent), upon which Parent may rely, that such sale, transfer or other
    disposition will be exempt from registration under the Securities Act;
 
        (c) such sale, transfer or other disposition is effected pursuant to an
    effective registration statement under the Securities Act; or
 
        (d) an authorized representative of the SEC shall have rendered written
    advice to Affiliate to the effect that the SEC would take no action, or that
    the staff of the SEC would not recommend that the SEC take action, with
    respect to such proposed sale, transfer or other disposition, and a copy of
    such written advice and all other related communications with the SEC shall
    have been delivered to Parent.
 
    3.  STOP TRANSFER INSTRUCTIONS; LEGEND.  Affiliate acknowledges and agrees
that (a) stop transfer instructions will be given to Parent's transfer agent
with respect to the Parent Shares, and (b) each certificate representing any of
such shares of Parent Common Stock or any substitutions thereof shall bear a
legend (together with any other legend or legends required by applicable state
securities laws or otherwise), stating in substance:
 
       THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
       TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT
       OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY
       NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED
       OR HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH
       RULE AND IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AS OF
       SEPTEMBER 9, 1998, BETWEEN THE REGISTERED HOLDER FIRST CONSULTING
       GROUP, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT THE PRINCIPAL
       OFFICES OF FIRST CONSULTING GROUP, INC.
 
    4.  COVENANTS RELATED TO POOLING OF INTERESTS.  In accordance with SEC Staff
Accounting Bulletin No. 65 ("SAB 65"), during the period contemplated by SAB 65,
until the earlier of (i) Parent's public announcement of financial results
covering at least 30 days of combined operations of Parent and Company or (ii)
the Merger Agreement is terminated in accordance with its terms, Affiliate will
not sell, exchange, transfer, pledge, distribute, or otherwise dispose of or
grant any option, establish any "short" or put-equivalent position with respect
to or enter into any similar transaction (through derivatives or otherwise)
intended or having the effect, directly or indirectly, to reduce its risk
relative to: (i) any shares of Company Common Stock, except pursuant to and upon
the consummation of the Merger; or (ii) any shares of Parent Common Stock
received by Affiliate in the Merger or any shares of Parent Common Stock
received by Affiliate upon exercise of options assumed by Parent in connection
with the Merger. Parent may, at its discretion, cause a restrictive legend
covering the restrictions referred to in this Section 4
 
                                     D-1-2
<PAGE>
to be placed on Parent Common Stock certificates issued to Affiliate in the
Merger and place a stock transfer notice consistent with the restrictions
referred to in this Section 4 with its transfer agent with respect to such
certificates, provided such restrictive legend shall be removed and/or notice
shall be countermanded promptly upon expiration of the necessity therefor at the
request of Affiliate.
 
    5.  PERMITTED TRANSFERS.  Notwithstanding anything to the contrary contained
in this Agreement, Affiliate (i) may transfer Affiliate's PRO RATA portion (of
the total number of shares available under the "de minimis" exception referred
to in this clause (i) to all affiliates of Parent and Company) of the "de
minimis" number of shares of Company Common Stock and Parent Common Stock
available for sale in accordance with SEC Staff Accounting Bulletin No. 76 (the
"DE MINIMIS POOL") contingent upon confirmation and approval by legal counsel
for Company and independent auditors to Company and Parent that such transfer
qualifies as within Affiliate's pro rata portion of the De Minimis Pool and does
not otherwise adversely affect the Parent's ability to account for the Merger as
a "pooling of interests" (ii) may (with the written consent of Parent, not to be
unreasonably withheld): (A) transfer shares of Company Common Stock or Parent
Common Stock to Company in payment of the exercise price of options to purchase
Company Common Stock; (B) transfer shares of Parent Common Stock in payment of
the exercise price of options to purchase Parent Common Stock; (C) transfer
shares of Company Common Stock or Parent Common Stock to any organization
qualified under Section 501(c)(3) of the Internal Revenue Code of 1986, as
amended, so long as such organization has traditionally been supported by
contributions from the general public (as opposed to being supported largely by
a specific donor); and (D) transfer shares of Company Common Stock or shares of
Parent Common Stock to a trust established for the benefit of Affiliate and/or
for the benefit of one or more members of Affiliate's family, or make a bona
fide gift of shares of Common Stock of Company or shares of Parent Common Stock
to one or more members of Affiliate's family, provided that in the case of a
transfer or gift pursuant to this clause (C) or (D), a transferee of such shares
agrees to be bound by the limitations set forth in this Agreement.
 
    6.  SPECIFIC PERFORMANCE.  The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement was not
performed in accordance with its specific terms or was otherwise breached.
Affiliate agrees that, in the event of any breach or threatened breach by
Affiliate of any covenant or obligation contained in this Agreement, each of
Parent and Company shall be entitled (in addition to any other remedy that may
be available to it, including monetary damages) to seek and obtain (a) a decree
or order of specific performance to enforce the observance and performance of
such covenant or obligation, and (b) an injunction restraining such breach or
threatened breach.
 
    7.  INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of Affiliate
set forth in this Affiliate Agreement shall be construed as independent of any
other agreement or arrangement between Affiliate, on the one hand, and Company
or Parent, on the other. The existence of any claim or cause of action by
Affiliate against Company or Parent shall not constitute a defense to the
enforcement of any of such covenants or obligations against Affiliate.
 
    8.  NOTICES.  Any notice or other communication required or permitted to be
delivered under this Agreement shall be in writing and shall be deemed properly
delivered, given and received when delivered (by hand, by registered mail, by
courier or express delivery service or by facsimile confirmation) to the address
or facsimile telephone number set forth beneath the name of such party below (or
to such other address or facsimile telephone number as such party shall have

Affiliate will not sell, exchange, transfer, pledge, distribute, or otherwise
dispose of or grant any option, establish any "short" or put-equivalent position
with respect to or enter into any similar transaction (through derivatives or
otherwise) intended or having the effect, directly or indirectly, to reduce its
risk relative to any Parent shares. Parent may, at its discretion, place a stock
transfer notice consistent with the restrictions referred to in this Section 2
with its transfer agent with respect to such certificates, provided such
restrictive legend shall be removed and/or notice shall be countermanded
promptly upon expiration of the necessity therefor at the request of Affiliate.
 
    3.  PERMITTED TRANSFERS.  Notwithstanding anything to the contrary contained
in this Agreement, Affiliate may (i) transfer a "de minimis" amount of Parent
Common Stock as contemplated by SEC Staff Accounting Bulletin No. 76 contingent
upon consultation with legal counsel for Parent as to whether such transfer
qualifies as "de minimis" and (ii) may (with the written consent of Parent, not
to be unreasonably withheld): (A) transfer shares of Parent Common Stock in
payment of the exercise price of options to purchase Parent Common Stock; (B)
transfer shares of Parent Common Stock to any organization qualified under
Section 501(c)(3) of the Internal Revenue Code of 1986, as amended, so long as
such organization has traditionally been supported by contributions from the
general public (as opposed to being supported largely by a specific donor); and
(C) transfer shares of Parent Common Stock to a trust established for the
benefit of Affiliate and/or for the benefit of one or more members of
Affiliate's family, or make a bona fide gift of Parent Common Stock to one or
more members of Affiliate's family, provided that in the case of a transfer or
gift pursuant to this clause (B) or (C), a transferee of such shares agrees to
be bound by the limitations set forth in this Agreement.
 
    4.  SPECIFIC PERFORMANCE.  The parties agree that irreparable damage would
occur in the event that any of the provisions of this Agreement was not
performed in accordance with its specific terms or was otherwise breached.
Affiliate agrees that, in the event of any breach or threatened breach by
Affiliate of any covenant or obligation contained in this Agreement, Parent
shall be entitled (in addition to any other remedy that may be available to it,
including monetary damages) to seek and obtain (a) a decree or order of specific
performance to enforce the observance and performance of such covenant or
obligation, and (b) an injunction restraining such breach or threatened breach.
 
    5.  INDEPENDENCE OF OBLIGATIONS.  The covenants and obligations of Affiliate
set forth in this Affiliate Agreement shall be construed as independent of any
other agreement or arrangement between Affiliate, on the one hand, and Parent,
on the other. The existence of any claim or cause of action by Affiliate against
Parent shall not constitute a defense to the enforcement of any of such
covenants or obligations against Affiliate.
 
    6.  NOTICES.  Any notice or other communication required or permitted to be
delivered under this Agreement shall be in writing and shall be deemed properly
delivered, given and received when delivered (by hand, by registered mail, by

2.  REGISTRATION RIGHTS.
 
    2.1  DEMAND REGISTRATION.
 
    (a) Subject to the conditions of this Section 2.1, if Parent shall receive a
written request from the Holders of at least fifty percent (50%) of the
Registrable Securities then outstanding and owned by the Holders (the
"INITIATING HOLDERS") that Parent file a registration statement under the
Securities Act covering the registration of any amount of Registrable Securities
then outstanding (a "QUALIFIED PUBLIC OFFERING"), then Parent shall, within
fifteen (15) days of the receipt thereof, give written notice of such request to
all Holders, and to certain other holders of Parent Common Stock determined by
Parent ("OTHER HOLDERS"), and subject to the limitations of this Section 2.1,
use commercially reasonable efforts to file a registration statement, as soon as
practicable but in no event later than ninety (90) days after the date of such
written request, registering under the Securities Act all Registrable Securities
that the Holders and Other Holders request to be registered.
 
    (b) If the Initiating Holders intend to distribute the Registrable
Securities covered by their request by means of an underwriting, they shall so
advise Parent as a part of their request made pursuant to this Section 2.1 and
Parent shall include such information in the written notice referred to in
Section 2.1(a). In such event, the right of any Holder or any Other Holder to
include its Registrable Securities in such registration shall be conditioned
upon such Holder's and Other Holder's participation in such underwriting and the
inclusion of such Holder's and such Other Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders and Other Holders
proposing to distribute their securities through such underwriting shall enter
into an underwriting agreement in customary form with the underwriter or
underwriters mutually selected for such underwriting by Parent and a majority in
interest of the Initiating Holders. Notwithstanding any other provision of this
Section 2.1, if the underwriter advises Parent that marketing factors require a
limitation of the number of securities to be underwritten (including Registrable
Securities) or restricts the underwriter's ability to conduct such offering then
Parent shall so advise all Holders and all Other Holders of Registrable
Securities which would otherwise be underwritten pursuant hereto, and the number
of shares that may be included in the underwriting shall be allocated to the
Holders and the Other Holders of Registrable Securities on a PRO RATA basis
based on the number of Registrable Securities held by all such Holders
(including the Initiating Holders) and the Other Holders; PROVIDED, HOWEVER,
that the number of Registrable Securities held by Other Holders to be included
in such underwriting and registration shall not exceed thirty-five percent (35%)
of the total number of shares of Registrable Securities proposed to be
distributed by means of the proposed underwriting; and, PROVIDED, FURTHER, that
the number of Registrable Securities to be allocated to the Holders shall not be
less than 2,000,000 shares of Parent Common Stock unless the number of
Registrable Securities to be included in the proposed underwriting is less than
2,000,000 shares of Parent Common Stock, in which case the entire amount of
Registrable Securities to be included in the proposed underwriting shall be
allocated to the Holders. Any Registrable Securities excluded or withdrawn from
such underwriting shall be withdrawn from the registration.
 
                                      E-2
<PAGE>
    (C) Parent shall not be required to file with the Commission a registration
statement or effect a registration pursuant to this Section 2.1:
 
        (i) during the period contemplated by Commission Staff Accounting
    Bulletin No. 65 until Parent's public announcement of financial results
    covering at least thirty (30) days of combined operations of Parent and the
    Company;
 
        (ii) after the date which is eighteen (18) months after the date of this
    Agreement;
 
       (iii) after Parent has effected one (1) registration pursuant to this
    Section 2.1, and such registration has been declared or ordered effective;
    or
 
        (iv) during any period starting with the date of filing of, and ending
    on the date one hundred eighty (180) days following, the effective date of a
    registration statement (other than registration statements relating to
    employee benefit plans) filed by the Company with the Commission; PROVIDED,
    HOWEVER, that Parent agrees that it will note file a registration statement
    with the Commission until 90 days after the end of the period described in
    clause (i) above.
 
    2.2  PIGGYBACK REGISTRATIONS.
 
    (a) Parent shall notify all Holders and Other Holders of Registrable
Securities in writing at least fifteen (15) days prior to the filing of any
registration statement under the Securities Act for purposes of distributing
securities of Parent by means of an underwritten public offering and will afford
each such Holder and Other Holder an opportunity to include in such registration
statement all or part of such Registrable Securities held by such Holder or
Other Holder. Each Holder and Other Holder desiring to include in any such
registration statement all or any part of the Registrable Securities held by it
shall, within fifteen (15) days after the above-described notice from Parent, so
notify Parent in writing. The right of any such Holder or Other Holder to be
included in a registration pursuant to this Section 2.2 shall be conditioned
upon such Holder's or Other Holder's participation in such underwriting and the
inclusion of such Holder's or Other Holder's Registrable Securities in the
underwriting to the extent provided herein. All Holders and Other Holders
proposing to distribute their Registrable Securities through such underwriting
shall enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting by Parent.
Notwithstanding any other provision of this Agreement, if the underwriter
determines in good faith that marketing factors require a limitation of the
number of shares to be underwritten, the number of shares that may be included
in the underwriting shall be allocated: first, to Parent; and second, to the
Holders and Other Holders of Registrable Securities on a PRO RATA basis based on
the total number of Registrable Securities held by them. No such reduction shall
(i) reduce the securities being offered by Parent for its own account to be
included in the registration and underwriting, or (ii) reduce the amount of
securities of the selling Holders of Registrable Securities included in the
registration below thirty percent (30%) of the total amount of securities
included in such registration, unless such offering registration does not
include shares of any other selling shareholders, including Other Holders, in
which event any or all of the Registrable Securities of the Holders may be
excluded in accordance with the immediately preceding sentence. If any Holder or
Other Holder disapproves of the terms of any such underwriting, such Holder or
Other Holder may elect to withdraw therefrom by written notice to Parent and the
underwriter, delivered at least ten (10) business days prior to the effective
date of the registration statement. Any Registrable Securities excluded or
withdrawn from such underwriting shall be excluded and withdrawn from the
registration. For any Holder or Other Holder which is a partnership or
corporation, the partners, retired partners and shareholders of such Holder or
Other Holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing person shall be
deemed to be a single "Holder" or Other Holder, as the case may be, and any PRO
RATA reduction with respect to such "Holder" or "Other Holder" shall be based
upon the aggregate amount of shares owned by all entities and individuals
included in such "Holder" or "Other Holder," as defined in this sentence. The
Holder's rights and Parent's obligations under this Section 2.2 shall expire on
the third anniversary of this Agreement.
 
                                      E-3
<PAGE>
    (b) Parent shall have the right to terminate or withdraw any registration
initiated by it under this Section 2.2 prior to the effectiveness of such
registration whether or not any Holder or Other Holder has elected to include
securities in such registration. The registration expenses of such withdrawn
registration shall be borne by Parent in accordance with Section 3.5 hereof.
 
3.  REGISTRATION PROCEDURES.
 
    3.1  REGISTRATION PROCEDURES PURSUANT TO SECTION 2.  In connection with
Parent's obligations to effect the Registration of any Registrable Securities
pursuant to Section 2 hereof, Parent shall:
 
        (a) prepare and file with the Commission the registration statement with
    respect to such Registrable Securities required under Section 2.1(a)
    provided that before filing a registration statement or prospectus or any
    amendments or supplements thereto, Parent will furnish to Holders' and Other
    Holders' counsel copies of all such documents proposed to be filed but only
    those portions of such documents relating to the Holders and Other Holders
    will be subject to the reasonable review of their respective counsel; and
    Parent shall use commercially reasonable efforts to cause such registration
    statement to become effective as soon as practicable;
 
        (b) prepare and file with the Commission such amendments and supplements
    to the registration statement and the prospectus used in connection
    therewith as may be necessary to maintain the effectiveness of the
    registration statement (for the applicable periods specified in Section 2.1
    hereof), and comply with the provisions of the Securities Act with respect
    to the disposition of all of the Registrable Securities during such
    applicable period in accordance with the intended methods of disposition by
    the Holders and Other Holders as set forth in the registration statement;
 
        (c) promptly notify the Holders and Other Holders of the Registrable
    Securities being registered and provide copies of all related documents (i)
    when a registration statement, the prospectus or any prospectus supplement
    or any amendment has been filed, and, with respect to a registration
    statement or any post-effective amendment, when the same has become
    effective, (ii) of any request by the Commission for amendments or
    supplements to a registration statement or the prospectus or for additional
    or supplemental information, (iii) of the issuance by the Commission of any
    stop order suspending the effectiveness of a registration statement or the
    written threat or initiation of any proceedings for that purpose, (iv) of
    the receipt by Parent of any notification with respect to the suspension of
    the qualification of the Registrable Securities for sale in any jurisdiction
    or the written threat or initiation of any proceeding for that purpose, or
    (v) at any time when a prospectus is required to be delivered under the
    Securities Act in connection with any registration statement, (A) of the
    happening of any event as a result of which such registration statement,
    prospectus, any prospectus supplement, or any document incorporated by
    reference in any of the foregoing contains an untrue statement of a material
    fact or omits to state any material fact required to be stated therein or
    necessary to make the statements therein, in the light of the circumstances
    under which they are made, not misleading or (B) that Parent is in
    possession of material information that it deems advisable not to disclose
    in a registration statement;
 
        (d) make reasonable best efforts to obtain the withdrawal of any order
    suspending the effectiveness of a registration statement or any
    post-effective amendment thereto or any state filing made in connection
    therewith at the earliest practicable date;
 
        (e) furnish to the Holders and Other Holders of the securities being
    sold such number of copies of the registration statement, each such
    amendment and supplement thereto (in each case including all exhibits
    thereto), the prospectus included in the registration statement and such
    other documents as the Holders or Other Holders may reasonably request in
    order to facilitate the disposition of the Registrable Securities being
    offered;
 
        (f) cause all such Registrable Securities to be listed on each
    securities exchange or market system on which the Parent Common Stock is
    then listed;
 
                                      E-4
<PAGE>
        (g) otherwise use commercially reasonable efforts to comply with all
    applicable rules and regulations of the Commission;
 
        (h) use commercially reasonable efforts to (i) register or qualify the
    Registrable Securities under such other securities laws or Blue Sky laws of
    such jurisdictions as the Holders or Other Holders shall reasonably request,
    (ii) keep such registrations or qualifications in effect for so long as each
    of the registration statements remains in effect and (iii) take any and all
    such actions as may be reasonably necessary or advisable to enable the
    Holders and Other Holders of Registrable Securities being sold to consummate
    the disposition in such jurisdictions of such Registrable Securities;
    PROVIDED, HOWEVER, that Parent shall not be required for any such purpose to
    (A) qualify generally to do business as a foreign corporation in any
    jurisdiction wherein it would not otherwise be required to qualify or (B)
    consent to general service of process in any such jurisdiction; and
 
        (i) cooperate with the Holders and Other Holders to effect the offering
    and to facilitate the timely preparation and delivery of certificates
    representing Registrable Securities to be sold under the registration
    statement and not bearing any restrictive legends and such other actions as
    may be reasonably necessary to complete the offering.
 
    3.2  SUPPLEMENTS; AMENDMENTS.  Upon the occurrence of any event contemplated
by Section 3.1(c)(v)(A), Parent shall, as soon as reasonably practicable,
prepare and furnish to each Holder and Other Holder a reasonable number of
copies of a prospectus supplemented or amended so that, as thereafter delivered
to the purchasers of Registrable Securities, such prospectus shall not contain
an untrue statement of a material fact or omit to state a material fact required
to bc stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading. The Holders and
Other Holders agree that upon receipt of any notice from Parent of the happening
of any event of the kind described in Section 3. l(c)(v)(A), the Holders and
Other Holders shall forthwith discontinue the disposition of the Registrable
Securities, until each Holder and Other Holder receives copies of such amended
or supplemented registration statement or prospectus, and if so directed by
Parent, the Holders and Other Holders shall deliver to Parent all copies, other
than permanent file copies, then in the Holders' or Other Holders' possession of
the prospectus covering such Registrable Securities at the time of receipt of
such notice. The Holders and Other Holders agree that upon receipt of any notice
from Parent of the happening of any circumstance described in Section
3.1(c)(v)(B), the Holders and Other Holders shall forthwith discontinue the
disposition of the Registrable Securities until Parent notifies the Holders and
Other Holders of the ceasing of such circumstances.
 
    3.3  HOLDER INFORMATION.  Parent may require each Holder and Other Holder to
furnish to Parent such information regarding the Holders and Other Holders and
the distribution of the Registrable Securities as Parent may from time to time
reasonably request in order to comply with the Securities Act. The Holders and
Other Holders agree to notify Parent as promptly as practicable of any
inaccuracy or change in information previously furnished by them to Parent or of
the happening of any event in either case as a result of which any prospectus
contains an untrue statement of a material fact regarding the Holders or Other
Holders or the distribution of such Registrable Securities or omits to state any
material fact regarding the Holders or the distribution of such Registrable
Securities required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they are made, not
misleading, and to furnish promptly to Parent any additional information
required to correct or update any previously furnished information or required
so that such prospectus shall not contain with respect to such person or the
distribution of such Registrable Securities an untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein not misleading in light of the circumstances then
existing.
 
    3.4  STOP TRANSFER INSTRUCTIONS; LEGEND.  The Holders and Other Holders
agree and understand that, except as contemplated in this Agreement, the sale or
other disposition thereof by the Holders and Other Holders will not be,
registered under the Securities Act or the securities laws of any state and that
such
 
                                      E-5
<PAGE>
shares may be sold or disposed of only in one (1) or more transactions
registered under the Securities Act and, where applicable, such state laws or as
to which an exemption from the registration requirements of the Securities Act
and, where applicable, such state laws is available. The Holders and Other
Holders acknowledge that, except as expressly set forth in this Agreement, the
Holders and Other Holders have no right to require Parent to cause the
registration of any Registrable Securities. The Holders and Other Holders
understand and agree that each certificate representing any Registrable
Securities (each, a "CERTIFICATE") shall be subject to stop transfer
instructions and shall bear a legend substantially as follows:
 
       "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
       TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT
       OF 1933 APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY
       NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED
       OR HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH
       RULE AND IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT DATED AS OF
       SEPTEMBER 9, 1998, BETWEEN THE REGISTERED HOLDER HEREOF FIRST
       CONSULTING GROUP, INC., A COPY OF WHICH AGREEMENT IS ON FILE AT
       THE PRINCIPAL OFFICES OF FIRST CONSULTING GROUP, INC."
 
    Parent hereby agrees that it will, upon the request of a Holder or Other
Holder, eliminate any stop transfer instructions and any restrictive legend on
any certificates representing the Registrable Securities if (i) in the opinion
of counsel, which counsel and opinion (in form, scope and substance) shall be
reasonably satisfactory to Parent, the Holders or Other Holders are entitled to
sell or dispose of the Registrable Securities represented by such Certificate
without registration or (ii) such shares are herein disposed of by the Holders
or Other Holders under a registration statement pursuant to Section 2 herein and
in compliance with the Securities Act and applicable state securities laws.
 
    3.5  EXPENSES OF REGISTRATION.  Parent shall bear and pay all expenses other
than underwriting discounts and commissions relating to Registrable Securities
incurred in connection with each registration, filing or qualification pursuant
to Section 2, including (without limitation) all registration, filing, and
qualification fees, printing, and accounting fees, fees and expenses of
compliance with securities or blue sky laws, fees and disbursements of counsel
for Parent, but Parent shall not pay the fees and disbursements of counsel and
accountants for the Holders and Other Holders. Parent shall not, however, be
required to pay for expenses of any registration proceeding begun pursuant to
Section 2.1, the request of which has been subsequently withdrawn by the
Initiating Holders unless the withdrawal is based upon material adverse
information concerning Parent of which the Initiating Holders were not aware at
the time of such request. If the Holders and Other Holders are required to pay
the registration expenses, such expenses shall be borne by the holders of
securities (including Registrable Securities) requesting such registration in
proportion to the number of shares for which registration was requested.
 
    3.6  DELAY OF REGISTRATION.  For a period not to exceed sixty (60) days,
Parent shall not be obligated to prepare and file, or be prevented from delaying
or abandoning, or by written notice to the Holders and Other Holders, may
suspend the use of (and the Holders and Other Holders hereby agree not to use a
registration statement during such period) a registration statement pursuant to
this Agreement at any time when Parent, in its good faith judgment, reasonably
believes:
 
        (i) that the filing thereof at the time requested, or the offering of
    Parent Common Stock pursuant thereto, would be seriously detrimental to the
    Company and its stockholders or
 
        (ii) (a) that the filing thereof at the time requested, or the offering
    of Parent Common Stock pursuant thereto, would materially and adversely
    affect (1) a pending or scheduled public offering or private placement of
    Parent securities, (2) an acquisition, merger, consolidation or similar
    transaction by or of Parent, (3) pre-existing and continuing negotiations,
    discussions or pending proposals with respect to any of the foregoing
    transactions or (4) the financial condition of Parent in view of the
 
                                      E-6
<PAGE>
    disclosure of any pending or threatened litigation, claim, assessment or
    governmental investigation which might be required thereby, and (b) that the
    failure to disclose any material information with respect to the foregoing
    items (1), (2), (3) or (4) would cause a violation of the Securities Act or
    the Exchange Act.
 
    In the event Parent, in good faith, reasonably believes that such conditions
are continuing after such sixty (60)-day period, it may, with the consent of the
holders of a majority of the shares of Parent Common Stock subject (or to be
subject) to the registration statement, which consent shall not be unreasonably
withheld, extend such sixty (60)-day period for an additional thirty (30) days.
Any further delay shall require the consent of the holders of all such shares.
 
    3.7  BLACKOUT PERIODS.  Notwithstanding any other provision of this
Agreement, the Holders and Other Holders understand that there may be periods
during which the Company's Board of Directors may determine, in good faith, that
it is in the best interest of the Company and its stockholders to defer
disclosure of material non-public information and that during such periods sales
of Registrable Securities and the effectiveness of any registration statement
covering Registrable Securities may be suspended or delayed. Each Holder or
Other Holder of Registrable Securities agrees by acquisition of such Registrable
Securities that upon receipt of any notice from the Company of the development
of any material non-public information, such Holder or Other Holder will
forthwith discontinue such Holder's or Other Holders' disposition of Registrable
Securities pursuant to the registration statement relating to such Registrable
Securities until such Holder's or Other Holders' receipt of copies of an
appropriately supplemented or amended prospectus (the "BLACKOUT PERIOD") and, if
so directed by the Company, such Holder or Other Holder will use its best
efforts to deliver to the Company (at the Company's expense) all copies, other
than permanent file copies then in such Holder's or Other Holder's possession,
of the prospectus relating to such Registrable Securities current at the time of
receipt of such notice. Notwithstanding the foregoing, (i) the aggregate
duration of all Blackout Periods in any ninety (90) day period shall not exceed
thirty (30) days, and (ii) no Blackout Period will be imposed during the five
(5) trading days following the effectiveness of a registration statement.
 
4.  INDEMNIFICATION.
 
    4.1  INDEMNIFICATION BY PARENT.  In connection with any registration
statement which Parent may file pursuant to this Agreement, Parent shall, and it
hereby agrees to, indemnify and hold harmless each of the Holders, Other Holders
and each of their respective directors and officers, and each other person, if
any, which controls any such person within the meaning of the Securities Act,
from and against any and all losses, claims, damages or liabilities, and
expenses (including without limitation reasonable fees of counsel and any
amounts paid in any settlement effected with the consent of Parent) to which any
of the Holders, Other Holders and/or such director, officer or controlling
person thereof may become subject under the Securities Act, the common law or
otherwise, insofar as such losses, claims, damages or liabilities (or any
actions or proceedings, whether commenced or threatened and whether civil,
criminal or administrative, in respect thereof) or expenses arise out of or are
based upon (i) any untrue statement or alleged untrue statement of a material
fact contained in any registration statement, or any preliminary, final or
summary prospectus contained therein, or any amendment or supplement thereto or
(ii) any omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statement therein, in light of the
circumstances in which they were made, not misleading; PROVIDED, HOWEVER, that
Parent shall not be liable to any such person in any such case to the extent
that any such loss, claim, damage, liability (or action or proceeding, whether
commenced or threatened, in respect thereof) or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any registration statement, or prospectus, or amendment
or supplement thereto, in reliance upon and in conformity with written
information furnished to Parent by such person expressly for use therein; and
provided, further, that Parent shall not be liable to any such person under the
indemnity agreement in this Section 4.1 to the extent that any such loss, claim,
damage or liability (or action or proceeding, whether commenced or threatened,
in respect thereof) or expense results from the
 
                                      E-7
<PAGE>
fact that Registrable Securities were sold to a person to whom there was not
sent or given a copy of the registration statement or prospectus or of the
prospectus as then amended or supplemented.
 
    4.2  INDEMNIFICATION BY THE HOLDERS.  In connection with any registration
statement in which the Registrable Securities held by a Holder or Other Holder
are registered, such Holder or Other Holder shall, and such Holder and Other
Holder hereby agrees to indemnify and hold harmless Parent, each director and
officer of Parent and such other person, if any, who controls Parent within the
meaning of the Securities Act, from and against any and all losses, claims,
damages or liabilities, and expenses (including without limitation reasonable
fees of counsel and any amounts paid in settlement effected with the consent of
such Holder and Other Holder not to be unreasonably withheld) to which Parent,
such director or officer or controlling person may become subject under the
Securities Act, the common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions or proceedings, whether commenced or
threatened and whether civil, criminal or administrative, in respect thereof) or
expenses arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact in or omission or alleged omission to state a
material fact required to be stated in any registration statement or any
prospectus contained therein, or any amendment or supplement thereto, or
necessary to make the statements therein not misleading, to the extent, but only
to the extent, such statement or alleged statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to Parent by such Holder or such Other Holder expressly for use
therein; provided, that the obligation to indemnify will be several and not
joint as to each Holder and Other Holder and will be limited to the net amount
of proceeds received by such Holder from the sale of Registrable Securities
pursuant to such registration statement.
 
    4.3  NOTICES OF CLAIMS, ETC.  Promptly after receipt by an indemnified party
hereunder of written notice of the commencement of any action or proceeding with
respect to which a claim for indemnification may be made pursuant to this
Section 4 or a written threat to commence such action or proceeding, such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party, give written notice thereof (including a reasonable
explanation of the circumstances in connection therewith and copies of all
writings received relating thereto) to the latter; PROVIDED, HOWEVER, that the
failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations under Section 4.1 or 4.2
hereof unless such failure to provide notice prejudices in any material way the
rights of the indemnifying party to conduct the defense of such action or
proceeding. In case any such action is brought against an indemnified party, the
indemnifying party shall be entitled to participate in and to assume the defense
thereof, jointly with any other indemnifying party similarly notified, to the
extent that it may wish, with counsel reasonably satisfactory to such
indemnified party, and after such notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party for any legal
or other expenses subsequently incurred by the latter in connection with the
defense thereof unless the indemnifying party has failed to assume the defense
of such claim and to employ counsel reasonably satisfactory to such indemnified
person. No indemnifying party shall consent to entry of any judgment or enter
into any settlement with respect to a claim made against an indemnified party
without the consent of the indemnified party, which consent shall not be
unreasonably withheld, or unless such judgment or settlement includes as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in connection with the
circumstances out of which the action or proceeding arose for all persons that
may be entitled to or obligated to provide indemnification or contribution under
this Section 4. No indemnified party shall consent to entry of any judgment or
enter into any settlement of any action the defense of which has been assumed by
an indemnifying party without the consent of such indemnifying party, which
consent shall not be unreasonably withheld. An indemnifying party who is not
entitled to, or elects not to assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one (1) counsel for all
parties indemnified by such indemnifying party with respect to such claim.
 
                                      E-8
<PAGE>
    4.4  CONTRIBUTION.  If for any reason the indemnification provided for in
Section 4.1 or Section 4.2 is unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, claims, damages, liabilities or
expenses specifically covered by the indemnification provisions set forth in
Section 4.1 or Section 4.2, then the indemnifying party shall contribute to the
amount paid or payable by the indemnified party as a result of such losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to
reflect the relative fault of the indemnifying party and the indemnified party,
as well as any other relevant equitable considerations; provided, that the
obligation to contribute will be individual to each Holder and Other Holder will
be limited to the net amount of proceeds received by such Holder or Other Holder
from the sale of Registrable Securities pursuant to such registration statement.
The relative fault of such indemnifying party and indemnified party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such indemnifying party or indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The parties hereto agree that it would not be
just and equitable if contribution pursuant to this Section 4.4 were determined
by pro rata allocation or by any other method of allocation which does not take
account of the equitable considerations referred to in the first sentence of
this paragraph. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11 (f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.
 
5.  MISCELLANEOUS.
 
    5.1  NON-ASSIGNABILITY OF REGISTRATION RIGHTS.  The rights to cause Parent,
or its successors or assigns to register Registrable Securities pursuant to this
Agreement are reserved solely for the use and benefit of the Holders and Other
Holders and may not be assigned or transferred by the Holders and Other Holders
to any other person other than to an Affiliate of such Holders or a Permitted
Transferee. A merger or consolidation of or transfer of all or substantially all
the assets of a Holder or Other Holder (a "FUNDAMENTAL TRANSACTION") shall not
be deemed an assignment for purposes of this Section 5.1 and the Registrable
Securities held by a Holder or Other Holder immediately prior to the
consummation of a Fundamental Transaction shall remain Registrable Securities
subsequent to such Fundamental Transaction.
 
    5.2  NOTICES.  All notices, requests, claims, demands, waivers and other
communications hereunder shall be in writing and shall be deemed to have been
duly given when delivered by hand, if delivered personally, by courier or by

shall be binding upon, shall inure to the benefit of and shall be enforceable by
the parties hereto and their respective successors.
 
    5.4  GOVERNING LAW.  This Agreement shall be governed by and construed in

cause the application of the domestic substantive laws of any other
jurisdiction,
 
    5.5  HEADINGS.  The descriptive headings of the several Sections and
paragraphs of this Agreement are for convenience of reference only, and do not
constitute a part of and shall not be deemed to limit or affect in any way any
of the provisions of this Agreement.
 
    5.6  ENTIRE AGREEMENT; AMENDMENTS.  This Agreement and other writings
referred to herein or delivered pursuant hereto which form a part hereof contain
the entire understanding of the parties with respect to its subject matter. This
Agreement supersedes all prior agreements and understandings between the parties
with respect to its subject matter, including the agreement relating to
registration rights set forth in Article V of that certain Common Stock and
Warrant Purchase Agreement between the Company and the Selling Parties (as
defined therein) dated June 30, 1995 and other related provisions thereof. This
Agreement may be amended and the observance of any term of this Agreement may be
waived only by a written instrument duly executed by Parent and each of the
Holders.
 
    5.7  COUNTERPARTS.  This Agreement may be executed in two (2) or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one (1) and the same instrument.
 
    5.8  CONSTRUCTION OF TERMS.  The singular may include the plural and vice
versa, unless the context clearly indicates to the contrary. The words "hereof,
"herein" and other similar compounds of the word "here" shall mean and refer to
the entire Agreement and not to any particular Section.
 
    5.9  SEVERABILITY OF PROVISIONS.  If any provision of this Agreement is
found to be unenforceable, the other provisions shall remain in effect.

                            BUSINESS CORPORATION LAW
 
    1930  DISSENTERS RIGHTS.--(a) General rule.--If any shareholder of a
domestic business corporation that is to be a party to a merger or consolidation
pursuant to a plan of merger or consolidation objects to the plan of merger or
consolidation and complies with the provisions of Subchapter D of Chapter 15
(relating to dissenters rights), the shareholder shall be entitled to the rights
and remedies of dissenting shareholders therein provided, if any. See also

fixed to determine the shareholders entitled to notice of and to vote at the
meeting at which a plan specified in any of Section 1930, 1931(d), 1932(c) or
1952(d) is to be voted on, are either:
 
        (i) listed on a national securities exchange; or

                                      F-1
<PAGE>
    (2) Paragraph (1) shall not apply to and dissenters rights shall be
available without regard to the exception provided in that paragraph in the case
of:
 
        (i) Shares converted by a plan if the shares are not converted solely
    into shares of the acquiring, surviving, new or other corporation or solely
    into such shares and money in lieu of fractional shares.
 
        (ii) Shares of any preferred or special class unless the articles, the
    plan or the terms of the transaction entitle all shareholders of the class
    to vote thereon and require for the adoption of the plan or the effectuation
    of the transaction the affirmative vote of a majority of the votes cast by
    all shareholders of the class.
 
       (iii) Shares entitled to dissenters rights under Section 1906(c)

exchange or other disposition all or substantially all of the shares, property
or assets of another corporation by the issuance of shares, obligations or
otherwise, with or without assuming the liabilities of the other corporation and
with or without the intervention of another corporation or other person, shall
not be entitled to the rights and remedies of dissenting shareholders provided
in this subchapter regardless of the fact, if it be the case, that the
acquisition was accomplished by the issuance of voting shares of the corporation
to be outstanding immediately after the acquisition sufficient to elect a
majority or more of the directors of the corporation.
 
    (c) Grant of optional dissenters rights.--The bylaws or a resolution of the
board of directors may direct that all or a part of the shareholders shall have
dissenters rights in connection with any corporate action or other transaction
that would otherwise not entitle such shareholders to dissenters rights.
 
    (d) Notice of dissenters rights.--Unless otherwise provided by statute, if a
proposed corporate action that would give rise to dissenters rights under this
subpart is submitted to a vote at a meeting of shareholders, there shall be
included in or enclosed with the notice of meeting:
 
        (1) a statement of the proposed action and a statement that the
    shareholders have a right to dissent and obtain payment of the fair value of
    their shares by complying with the terms of this subchapter; and
 
        (2) a copy of this subchapter.
 
    (e) Other statutes.--The procedures of this subchapter shall also be
applicable to any transaction described in any statute other than this part that
makes reference to this subchapter for the purpose of granting dissenters
rights.

    1572  DEFINITIONS.--The following words and phrases when used in this
subchapter shall have the meanings given to them in this Section unless the
context clearly indicates otherwise:
 
    "CORPORATION."  The issuer of the shares held or owned by the dissenter
    before the corporate action or the successor by merger, consolidation,
    division, conversion or otherwise of that issuer. A plan of division may
    designate which of the resulting corporations is the successor corporation
    for the purposes of this subchapter. The successor corporation in a division
    shall have sole responsibility for payments to dissenters and other
    liabilities under this subchapter except as otherwise provided in the plan
    of division.
 
                                      F-2
<PAGE>
    "DISSENTER."  A shareholder or beneficial owner who is entitled to and does
    assert dissenters rights under this subchapter and who has performed every
    act required up to the time involved for the assertion of those rights.
 
    "FAIR VALUE."  The fair value of shares immediately before the effectuation
    of the corporate action to which the dissenter objects taking into account
    all relevant factors, but excluding any appreciation or depreciation in
    anticipation of the corporate action.
 
    "INTEREST."  Interest from the effective date of the corporate action until
    the date of payment at such rate as is fair and equitable under all of the
    circumstances, taking into account all relevant factors including the
    average rate currently paid by the corporation on its principal bank loans.
 
    1573  RECORD AND BENEFICIAL HOLDERS AND OWNERS.--(a) Record holders of
shares.--A record holder of shares of a business corporation may assert
dissenters rights as to fewer than all of the shares registered in his name only
if he dissents with respect to all the shares beneficially owned by any one
person and discloses the name and address of the person or persons on whose
behalf he dissents. In that event, his rights shall be determined as if the
shares as to which he has dissented and his other shares were registered in the
names of different shareholders.
 
    (b) Beneficial owners of shares.--A beneficial owner of shares of a business
corporation who is not the record holder may assert dissenters rights with
respect to shares held on his behalf and shall be treated as a dissenting
shareholder under the terms of this subchapter if he submits to the corporation
not later than the time of the assertion of dissenters rights a written consent
of the record holder. A beneficial owner may not dissent with respect to some
but less than all shares of the same class or series owned by the owner, whether
or not the shares so owned by him are registered in his name.
 
    1574  NOTICE OF INTENTION TO DISSENT.--If the proposed corporate action is
submitted to a vote at a meeting of shareholders of a business corporation, any
person who wishes to dissent and obtain payment of the fair value of his shares
must file with the corporation, prior to the vote, a written notice of intention
to demand that he be paid the fair value of his shares if the proposed action is
effectuated, must effect no change in the beneficial ownership of his shares
from the date of such filing continuously through the effective date of the
proposed action and must refrain from voting his shares in approval of such
action. A dissenter who fails in any respect shall not acquire any right to
payment of the fair value of his shares under this subchapter. Neither a proxy
nor a vote against the proposed corporate action shall constitute the written
notice required by this section.
 
    1575  NOTICE TO DEMAND PAYMENT.--(a) General rule.--If the proposed
corporate action is approved by the required vote at a meeting of shareholders
of a business corporation, the corporation shall mail a further notice to all
dissenters who gave due notice of intention to demand payment of the fair value
of their shares and who refrained from voting in favor of the proposed action.
If the proposed corporate action is to be taken without a vote of shareholders,
the corporation shall send to all shareholders who are entitled to dissent and
demand payment of the fair value of their shares a notice of the adoption of the
plan or other corporate action. In either case, the notice shall:
 
        (1) State where and when a demand for payment must be sent and
    certificates for certificated shares must be deposited in order to obtain
    payment.
 
        (2) Inform holders of uncertificated shares to what extent transfer of
    shares will be restricted from the time that demand for payment is received.
 
        (3) Supply a form for demanding payment that includes a request for
    certification of the date on which the shareholder, or the person on whose
    beneficial shareholder dissents, acquired beneficial ownership of the
    shares.
 
        (4) Be accompanied by a copy of this subchapter.
 
                                      F-3
<PAGE>
    (b) Time for receipt of demand for payment.--The time set for receipt of the
demand and deposit of certificated shares shall be not less than 30 days from
the mailing of the notice.
 
    1576  FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC.--(a) Effect of
failure of shareholder to act.--A shareholder who fails to timely demand
payment, or fails (in the case of certificated shares) to timely deposit
certificates, as required by a notice pursuant to Section 1575 (relating to
notice to demand payment) shall not have any right under this subchapter to
receive payment of the fair value of his shares.
 
    (b) Restriction on uncertificated shares.--If the shares are not represented
by certificates, the business corporation may restrict their transfer from the
time of receipt of demand for payment until effectuation of the proposed
corporate action or the release of restrictions under the terms of Section
1577(a) (relating to failure to effectuate corporate action).
 
    (c) Rights retained by shareholder.--The dissenter shall retain all other
rights of a shareholder until those rights are modified by effectuation of the
proposed corporate action.
 
    1577  RELEASE OF RESTRICTIONS OR PAYMENT FOR SHARES.--(a) Failure to
effectuate corporate action.--Within 60 days after the date set for demanding
payment and depositing certificates, if the business corporation has not
effectuated the proposed corporate action, it shall return any certificates that
have been deposited and release uncertificated shares from any transfer
restrictions imposed by reason of the demand for payment.
 
    (b) Renewal of notice to demand payment.--When uncertified shares have been
released from transfer restrictions and deposited certificates have been
returned, the corporation may at any later time send a new notice conforming to
the requirements of Section 1575 (relating to notice to demand payment), with
like effect.
 
    (c) Payment of fair value of shares.--Promptly after effectuation of the
proposed corporate action, or upon timely receipt of demand for payment if the
corporate action has already been effectuated, the corporation shall either
remit to dissenters who have made demand and (if their shares are certificated)
have deposited their certificates the amount that the corporation estimates to
be the fair value of the shares, or give written notice that no remittance under
this Section will be made. The remittance or notice shall be accompanied by:
 
        (1) The closing balance sheet and statement of income of the issuer of
    the shares held or owned by the dissenter for a fiscal year ending not more
    than 16 months before the date of remittance or notice together with the
    latest available interim financial statements.
 
        (2) A statement of the corporation's estimate of the fair value of the
    shares.
 
        (3) A notice of the right of the dissenter to demand payment or
    supplemental payment, as the case may be, accompanied by a copy of this
    subchapter.
 
    (d) Failure to make payment.--If the corporation does not remit the amount
of its estimate of the fair value of the shares as provided by subSection (c),
it shall return any certificates that have been deposited and release
uncertificated shares from any transfer restrictions imposed by reason of the
demand for payment. The corporation may make a notation on any such certificate
or on the records of the corporation relating to any such uncertificated shares
that such demand has been made. If shares with respect to which notation has
been so made shall be transferred, each new certificate issued therefor or the
records relating to any transferred uncertificated shares shall bear a similar
notation, together with the name of the original dissenting holder or owner of
such shares. A transferee of such shares shall not acquire by such transfer any
rights in the corporation other than those which the original dissenter had
after making demand for payment of their fair value.
 
                                      F-4
<PAGE>
    1578  ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES.--(a) General rule--If
the business corporation gives notice of its estimate of the fair value of the
shares, without remitting such amount, or remits payment of its estimate of the
fair value of a dissenter's shares as permitted by Section 1577(c) (relating to
payment of fair value of shares) and the dissenter believes that the amount
stated or remitted is less than the fair value of his shares, he may send to the
corporation his own estimate of the fair value of the shares, which shall be
deemed a demand for payment of the amount or the deficiency.
 
    (b) Effect of failure to file estimate.--Where the dissenter does not file
his own estimate under subSection (a) within 30 days after the mailing by the
corporation of its remittance or notice, the dissenter shall be entitled to no
more than the amount stated in the notice or remitted to him by the corporation.
 
    1579  VALUATION PROCEEDINGS GENERALLY.--(a) General rule--Within 60 days
after the latest of:
 
        (1) Effectuation of the proposed corporate action;
 
        (2) Timely receipt of any demands for payment under Section 1575
    (relating to notice to demand payment); or
 
        (3) Timely receipt of any estimates pursuant to Section 1578 (relating
    to estimate by dissenter of fair value of shares); if any demands for
    payment remain unsettled, the business corporation may file in court an
    application for relief requesting that the fair value of the shares be
    determined by the court.
 
    (b) Mandatory joinder of dissenters.--All dissenters, wherever residing,
whose demands have not been settled shall be made parties to the proceeding as
in an action against their shares. A copy of the application shall be served on
each such dissenter. If a dissenter is a nonresident, the copy may be served on
him in the manner provided or prescribed by or pursuant to 42 Pa.C.S. Ch. 53
(relating to bases of jurisdiction and interstate and international procedure).
 
    (c) Jurisdiction of the court.--The jurisdiction of the court shall be
plenary and exclusive. The court may appoint an appraiser to receive evidence
and recommend a decision on the issue of fair value. The appraiser shall have
such power and authority as may be specified in the order of appointment or in
any amendment thereof.
 
    (d) Measure of recovery.--Each dissenter who is made a party shall be
entitled to recover the amount by which the fair value of his shares is found to
exceed the amount, if any, previously remitted, plus interest.
 
    (e) Effect of corporation's failure to file application.--If the corporation
fails to file an application as provided in subSection (a), any dissenter who
made a demand and who has not already settled his claim against the corporation
may do so in the name of the corporation at any time within 30 days after the
expiration of the 60-day period. If a dissenter does not file an application
within the 30-day period, each dissenter entitled to file an application shall
be paid the corporation's estimate of the fair value of the shares and no more,
and may bring an action to recover any amount not previously remitted.
 
    1580  COSTS AND EXPENSES OF VALUATION PROCEEDINGS.--(a) General rule.--The
costs and expenses of any proceeding under Section 1579 (relating to valuation
proceedings generally) including the reasonable compensation and expenses of the
appraiser appointed by the court, shall be determined by the court and assessed
against the business corporation except that any part of the costs and expenses
may be apportioned and assessed as the court deems appropriate against all or
some of the dissenters who are parties and whose action in demanding
supplemental payment under Section 1578 (relating to estimate by dissenter of
fair value of shares) the court finds to be dilatory, obdurate, arbitrary,
vexatious or in bad faith.
 
    (b) Assessment of counsel fees and expert fees where lack of good faith
appears.--Fees and expenses of counsel and of experts for the respective parties
may be assessed as the court deems appropriate against
 
                                      F-5
<PAGE>
the corporation and in favor of any or all dissenters if the corporation failed
to comply substantially with the requirements of this subchapter and may be
assessed against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses arc
assessed acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious
manner in respect to the rights provided by this subchapter.
 
    (c) Award of fees for benefits to other dissenters.--If the court finds that
the services of counsel for any dissenter were of substantial benefit to other
dissenters similarly situated and should not be assessed against the
corporation, it may award to those counsel reasonable fees to be paid out of the
amounts awarded to the dissenters who were benefited.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    FCG's Bylaws provide that FCG will indemnify its directors and executive
officers and may indemnify its other officers, employees and other agents to the
fullest extent permitted by Delaware law. FCG is also empowered under its Bylaws
to enter into indemnification contracts with its directors and officers and to
purchase insurance on behalf of any person it is required or permitted to
indemnify. Pursuant to this provision, FCG expects to enter into indemnification
agreements with each of its directors and executive officers.
 
    FCG has obtained officer and director liability insurance with respect to
liabilities arising out of certain matters, including matters arising under the
Securities Act. In addition, FCG's Certificate of Incorporation provides that,
to the fullest extent permitted by Delaware law, FCG's directors will not be
liable for monetary damages for breach of the directors' fiduciary duty of care
to FCG and its stockholders. This provision in the Certificate of Incorporation
does not eliminate the duty of care, and in appropriate circumstances, equitable
remedies such as an injunction or other forms of non-monetary relief would
remain available under Delaware law. Under current Delaware law, a director's
liability to FCG or its stockholders may not be limited with respect to any
breach of the director's duty of loyalty to FCG or its stockholders, for acts or
omissions not in good faith or involving intentional misconduct, for knowing
violations of law, for any transaction from which the director derived an
improper personal benefit, for improper transactions between the director and
FCG and for improper distributions to stockholders and loans to directors and
officers. This provision also does not affect a director's responsibilities
under any other laws such as the federal securities laws or state or federal
environmental laws.
 
    There is no pending litigation or proceeding involving a director or officer
of FCG as to which indemnification is being sought, nor is FCG aware of any
pending or threatened litigation that may result in claims for indemnification
by any director or officer.
 
    THE REGISTRANT HAS OBTAINED DIRECTORS' AND OFFICERS' LIABILITY INSURANCE
THAT COVERS CERTAIN LIABILITIES, INCLUDING LIABILITIES TO THE REGISTRANT AND ITS
STOCKHOLDERS.
 
    Pursuant to the Reorganization Agreement, all rights to indemnification
existing in favor of the persons serving as directors or officers of ISCG as of
the date of the Reorganization Agreement for acts and omissions occurring prior
to the Effective Time, as provided in the ISCG Bylaws and as provided in any
indemnification agreements between ISCG and said officers and directors shall
survive the Merger and shall be observed by FCG and the Surviving Corporation
for a period of not less than six years from the Effective Time. The
Reorganization Agreement also provides that from the Effective Time until the
third anniversary of the date on which the Merger becomes effective, the
Surviving Corporation shall maintain in effect, for the benefit of the persons
serving as directors and officers of ISCG as of the date of the Reorganization
Agreement with respect to acts or omissions occurring prior to the Effective
Time, the lesser of (i) the existing policy of directors' and officers'
liability insurance maintained by ISCG as of the date of the Reorganization
Agreement (the "Existing Policy") and (ii) the amount of coverage purchased by
150% of the amount of the last annual premium paid by ISCG prior to the date of
the Reorganization Agreement for the Existing Policy; provided, however, that
the Surviving Corporation may substitute for the Existing Policy a policy or
policies of comparable coverage.

into the Joint Proxy Statement/Prospectus.
 
    (c) ITEM 4(B) REPORTS
 
        See Appendices B-1 and B-2 to the Joint Proxy Statement/Prospectus.
 
ITEM 22. UNDERTAKINGS.
 
    (1) The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the Joint Proxy Statement/Prospectus
pursuant to Items 4, 10(b), 11 or 13 of Form S-4, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the Registration Statement
through the date of responding to the request.
 
    (2) The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.
 
    (3) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
                                      II-4

    (4) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Act") may be permitted to directors, officers and
controlling persons of the Registrant pursuant to the Amended and Restated
Certificate of Incorporation (the "Certificate of Incorporation") and the Bylaws
(the "Bylaws") of the Registrant and the Delaware General Corporation Law, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in a successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the
question has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
    (5) (A)  The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this Registration Statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
        (B)  The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (A) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the Registration Statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
